anchor

int anchor

This field is used when the component is smaller than its display area. It determines where, within the display area, to place the component.

There are three kinds of possible values: orientation relative, baseline relative and absolute. Orientation relative values are interpreted relative to the container's component orientation property, baseline relative values are interpreted relative to the baseline and absolute values are not. The absolute values are: CENTER, NORTH, NORTHEAST, EAST, SOUTHEAST, SOUTH, SOUTHWEST, WEST, and NORTHWEST. The orientation relative values are: PAGE_START, PAGE_END, LINE_START, LINE_END, FIRST_LINE_START, FIRST_LINE_END, LAST_LINE_START and LAST_LINE_END. The baseline relative values are: BASELINE, BASELINE_LEADING, BASELINE_TRAILING, ABOVE_BASELINE, ABOVE_BASELINE_LEADING, ABOVE_BASELINE_TRAILING, BELOW_BASELINE, BELOW_BASELINE_LEADING, and BELOW_BASELINE_TRAILING. The default value is CENTER.

This field is used when the component's display area is larger than the component's requested size. It determines whether to resize the component, and if so, how.

The following values are valid for fill:

• NONE: Do not resize the component.
• HORIZONTAL: Make the component wide enough to fill its display area horizontally, but do not change its height.
• VERTICAL: Make the component tall enough to fill its display area vertically, but do not change its width.
• BOTH: Make the component fill its display area entirely.

The default value is NONE.

See Also:

GridBagConstraints.clone()

gridheight

int gridheight

Specifies the number of cells in a column for the component's display area.

Use REMAINDER to specify that the component's display area will be from gridy to the last cell in the column. Use RELATIVE to specify that the component's display area will be from gridy to the next to the last one in its column.

gridheight should be a non-negative value and the default value is 1.

See Also:

GridBagConstraints.clone(), GridBagConstraints.gridwidth

gridwidth

int gridwidth

Specifies the number of cells in a row for the component's display area.

Use REMAINDER to specify that the component's display area will be from gridx to the last cell in the row. Use RELATIVE to specify that the component's display area will be from gridx to the next to the last one in its row.

gridwidth should be non-negative and the default value is 1.

tempY

int tempY

Temporary place holder for the y coordinate.

weightx

double weightx

Specifies how to distribute extra horizontal space.

The grid bag layout manager calculates the weight of a column to be the maximum weightx of all the components in a column. If the resulting layout is smaller horizontally than the area it needs to fill, the extra space is distributed to each column in proportion to its weight. A column that has a weight of zero receives no extra space.

If all the weights are zero, all the extra space appears between the grids of the cell and the left and right edges.

The default value of this field is 0. weightx should be a non-negative value.

See Also:

GridBagConstraints.clone(), GridBagConstraints.weighty

weighty

double weighty

Specifies how to distribute extra vertical space.

The grid bag layout manager calculates the weight of a row to be the maximum weighty of all the components in a row. If the resulting layout is smaller vertically than the area it needs to fill, the extra space is distributed to each row in proportion to its weight. A row that has a weight of zero receives no extra space.

If all the weights are zero, all the extra space appears between the grids of the cell and the top and bottom edges.

The default value of this field is 0. weighty should be a non-negative value.

This field holds the overrides to the row weights. If this field is non-null the values are applied to the gridbag after all of the rows weights have been calculated. If rowWeights[i] > weight for row i, then row i is assigned the weight in rowWeights[i]. If rowWeights has more elements than the number of rows, the excess elements are ignored - they do not cause more rows to be created.

Serialization Methods

readResolve

private Object readResolve()

The design of the SystemColor class assumes that the SystemColor object instances stored in the static final fields above are the only instances that can be used by developers. This method helps maintain those limits on instantiation by using the index stored in the value field of the serialized form of the object to replace the serialized object with the equivalent static object constant field of SystemColor. See the SystemColor.writeReplace() method for more information on the serialized form of these objects.

writeReplace

private Object writeReplace()
                     throws ObjectStreamException

Returns a specialized version of the SystemColor object for writing to the serialized stream.

Serial Data:

The value field of a serialized SystemColor object contains the array index of the system color instead of the rgb data for the system color. This index is used by the SystemColor.readResolve() method to resolve the deserialized objects back to the original static constant versions to ensure unique instances of each SystemColor object.

readObject

private void readObject(ObjectInputStream s)
                 throws IOException,

Reads default serializable fields from the stream. Reads from the stream a string and an array of bytes as additional data.

Serial Data:

the String is the name of one of CS_* constants defined in the ColorSpace class if the profile object is a profile for a predefined color space (for example "CS_sRGB"). The string is null otherwise.

The byte[] array is the profile data for the profile. It will usually be null for the predefined profiles.

If the string is recognized as a constant name for predefined color space the object will be resolved into profile obtained with getInstance(int cspace) and the profile data are ignored. Otherwise the object will be resolved into profile obtained with getInstance(byte[] data).

Throws:

Serial Data:

the String is the name of one of CS_* constants defined in the ColorSpace class if the profile object is a profile for a predefined color space (for example "CS_sRGB"). The string is null otherwise.

The byte[] array is the profile data for the profile. For predefined color spaces null is written instead of the profile data. If in the future versions of Java API new predefined color spaces will be added, future versions of this class may choose to write for new predefined color spaces not only the color space name, but the profile data as well so that older versions could still deserialize the object.

Deserializes this DragGestureEvent. This method first performs default deserialization for all non-transient fields. An attempt is then made to deserialize this object's List of gesture events as well. This is first attempted by deserializing the field events, because, in releases prior to 1.4, a non-transient field of this name stored the List of gesture events.

If the resulting FlavorMap is null, this object's FlavorMap is set to the default FlavorMap for this thread's ClassLoader. Next, this object's listeners are deserialized by reading a null-terminated sequence of 0 or more key/value pairs from the stream:

• If a key object is a String equal to dragSourceListenerK, a DragSourceListener is deserialized using the corresponding value object and added to this DragSource.

2. followed by a byte indicating the storage type of the original object as a hint (SERIAL_STORAGE_FLT_ARRAY)
3. followed by an integer indicating the number of path segments to follow (NP) or -1 to indicate an unknown number of path segments follows
4. followed by an integer indicating the total number of coordinates to follow (NC) or -1 to indicate an unknown number of coordinates follows (NC should always be even since coordinates always appear in pairs representing an x,y pair)
5. followed by a byte indicating the winding rule (WIND_EVEN_ODD or WIND_NON_ZERO)
6. followed by NP (or unlimited if NP < 0) sets of values consisting of a single byte indicating a path segment type followed by one or more pairs of float or double values representing the coordinates of the path segment
7. followed by a byte indicating the end of the path (SERIAL_PATH_END).

The following byte value constants are used in the serialized form of Path2D objects:

Constants

Constant Name	Byte Value	Followed by	Description
SERIAL_STORAGE_FLT_ARRAY	0x30		A hint that the original Path2D object stored the coordinates in a Java array of floats.
SERIAL_STORAGE_DBL_ARRAY	0x31		A hint that the original Path2D object stored the coordinates in a Java array of doubles.
SERIAL_SEG_FLT_MOVETO	0x40	2 floats	A moveTo path segment follows.
SERIAL_SEG_FLT_LINETO	0x41	2 floats	A lineTo path segment follows.
SERIAL_SEG_FLT_QUADTO	0x42	4 floats	A quadTo path segment follows.
SERIAL_SEG_FLT_CUBICTO	0x43	6 floats	A curveTo path segment follows.
SERIAL_SEG_DBL_MOVETO	0x50	2 doubles	A moveTo path segment follows.
SERIAL_SEG_DBL_LINETO	0x51	2 doubles	A lineTo path segment follows.
SERIAL_SEG_DBL_QUADTO	0x52	4 doubles	A curveTo path segment follows.
SERIAL_SEG_DBL_CUBICTO	0x53	6 doubles	A curveTo path segment follows.
SERIAL_SEG_CLOSE	0x60		A closePath path segment.
SERIAL_PATH_END	0x61		There are no more path segments following.

Serialization Overview

Class Class is special cased within the Serialization Stream Protocol. A Class instance is written initially into an ObjectOutputStream in the following format:

      TC_CLASS ClassDescriptor
      A ClassDescriptor is a special cased serialization of
      a java.io.ObjectStreamClass instance.
 

A new handle is generated for the initial time the class descriptor is written into the stream. Future references to the class descriptor are written as references to the initial class descriptor instance.

readObject

private void readObject(ObjectInputStream s)
                 throws IOException,
                        ClassNotFoundException

Reads a Throwable from a stream, enforcing well-formedness constraints on fields. Null entries and self-pointers are not allowed in the list of suppressedExceptions. Null entries are not allowed for stack trace elements. A null stack trace in the serial form results in a zero-length stack element array. A single-element stack trace whose entry is equal to new StackTraceElement("", "", null, Integer.MIN_VALUE) results in a null stackTrace field. Note that there are no constraints on the value the cause field can hold; both null and this are valid values for the field.

Throws:

IOException

ClassNotFoundException

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Write a Throwable object to a stream. A null stack trace field is represented in the serial form as a one-element array whose element is equal to new StackTraceElement("", "", null, Integer.MIN_VALUE).

Throws:

IOException

Serialized Fields

cause

Throwable cause

The throwable that caused this throwable to get thrown, or null if this throwable was not caused by another throwable, or if the causative throwable is unknown. If this field is equal to this throwable itself, it indicates that the cause of this throwable has not yet been initialized.

Since:

1.4

detailMessage

String detailMessage

Specific details about the Throwable. For example, for FileNotFoundException, this contains the name of the file that could not be found.

stackTrace

StackTraceElement[] stackTrace

The stack trace, as returned by Throwable.getStackTrace(). The field is initialized to a zero-length array. A null value of this field indicates subsequent calls to Throwable.setStackTrace(StackTraceElement[]) and Throwable.fillInStackTrace() will be no-ops.

Since:

1.4

suppressedExceptions

List<Throwable> suppressedExceptions

The list of suppressed exceptions, as returned by Throwable.getSuppressed(). The list is initialized to a zero-element unmodifiable sentinel list. When a serialized Throwable is read in, if the suppressedExceptions field points to a zero-element list, the field is reset to the sentinel value.

readObject

private void readObject(ObjectInputStream s)
                 throws IOException,
                        ClassNotFoundException

Reconstitute the MethodType instance from a stream (that is, deserialize it). This instance is a scratch object with bogus final fields. It provides the parameters to the factory method called by readResolve. After that call it is discarded.

Throws:

IOException - if there is a problem reading the object

ClassNotFoundException - if one of the component classes cannot be resolved

See Also:

MethodType.readResolve(), MethodType.writeObject(java.io.ObjectOutputStream)

readResolve

private Object readResolve()

Resolves and initializes a MethodType object after serialization.

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Save the MethodType instance to a stream.

Serial Data:

For portability, the serialized format does not refer to named fields. Instead, the return type and parameter type arrays are written directly from the writeObject method, using two calls to s.writeObject as follows:

s.writeObject(this.returnType());
s.writeObject(this.parameterArray());
 

The deserialized field values are checked as if they were provided to the factory method methodType. For example, null values, or void parameter types, will lead to exceptions during deserialization.

Throws:

IOException - if there is a problem writing the object

There are no serializable fields for MethodType.

readObject

private void readObject(ObjectInputStream s)
                 throws IOException,

Reconstitute the BigInteger instance from a stream (that is, deserialize it). The magnitude is read in as an array of bytes for historical reasons, but it is converted to an array of ints and the byte array is discarded. Note: The current convention is to initialize the cache fields, bitCountPlusOne, bitLengthPlusOne and lowestSetBitPlusTwo, to 0 rather than some other marker value. Therefore, no explicit action to set these fields needs to be taken in readObject because those fields already have a 0 value by default since defaultReadObject is not being used.

Throws:

IOException

ClassNotFoundException

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Save the BigInteger instance to a stream. The magnitude of a BigInteger is serialized as a byte array for historical reasons. To maintain compatibility with older implementations, the integers -1, -1, -2, and -2 are written as the values of the obsolete fields bitCount, bitLength, lowestSetBit, and firstNonzeroByteNum, respectively. These values are compatible with older implementations, but will be ignored by current implementations.

readObject for custom serialization.

This method reads this object's serialized form for this class as follows:

The readObject method is invoked on in to read this object's unique identifier (a UID instance).

Next, the readUTF method is invoked on in to read the external ref type name of the RemoteRef instance for this object's activator. Next, the RemoteRef instance is created of an implementation-specific class corresponding to the external ref type name (returned by readUTF), and the readExternal method is invoked on that RemoteRef instance to read the external form corresponding to the external ref type name.

Note: If the external ref type name is "UnicastRef", "UnicastServerRef", "UnicastRef2", "UnicastServerRef2", or "ActivatableRef", a corresponding implementation-specific class must be found, and its readExternal method must read the serial data for that external ref type name as specified to be written in the serialData documentation for this class. If the external ref type name is any other string (of non-zero length), a ClassNotFoundException will be thrown, unless the implementation provides an implementation-specific class corresponding to that external ref type name, in which case the RemoteRef will be an instance of that implementation-specific class.

Throws:

This method writes this object's serialized form for this class as follows:

The writeObject method is invoked on out passing this object's unique identifier (a UID instance) as the argument.

Next, the getRefClass method is invoked on the activator's RemoteRef instance to obtain its external ref type name. Next, the writeUTF method is invoked on out with the value returned by getRefClass, and then the writeExternal method is invoked on the RemoteRef instance passing out as the argument.

Serial Data:

The serialized data for this class comprises a java.rmi.server.UID (written with ObjectOutput.writeObject) followed by the external ref type name of the activator's RemoteRef instance (a string written with ObjectOutput.writeUTF), followed by the external form of the RemoteRef instance as written by its writeExternal method.

The external ref type name of the RemoteRef instance is determined using the definitions of external ref type names specified in the RemoteObject writeObject method serialData specification. Similarly, the data written by the writeExternal method and read by the readExternal method of RemoteRef implementation classes corresponding to each of the defined external ref type names is specified in the RemoteObject writeObject method serialData specification.

readObject

private void readObject(ObjectInputStream in)
                 throws IOException,
                        ClassNotFoundException

readObject for custom serialization.

This method reads this object's serialized form for this class as follows:

The readUTF method is invoked on in to read the external ref type name for the RemoteRef instance to be filled in to this object's ref field. If the string returned by readUTF has length zero, the readObject method is invoked on in, and than the value returned by readObject is cast to RemoteRef and this object's ref field is set to that value. Otherwise, this object's ref field is set to a RemoteRef instance that is created of an implementation-specific class corresponding to the external ref type name returned by readUTF, and then the readExternal method is invoked on this object's ref field.

If the external ref type name is "UnicastRef", "UnicastServerRef", "UnicastRef2", "UnicastServerRef2", or "ActivatableRef", a corresponding implementation-specific class must be found, and its readExternal method must read the serial data for that external ref type name as specified to be written in the serialData documentation for this class. If the external ref type name is any other string (of non-zero length), a ClassNotFoundException will be thrown, unless the implementation provides an implementation-specific class corresponding to that external ref type name, in which case this object's ref field will be set to an instance of that implementation-specific class.

Throws:

IOException

ClassNotFoundException

writeObject

private void writeObject(ObjectOutputStream out)
                  throws IOException

writeObject for custom serialization.

This method writes this object's serialized form for this class as follows:

The getRefClass method is invoked on this object's ref field to obtain its external ref type name. If the value returned by getRefClass was a non-null string of length greater than zero, the writeUTF method is invoked on out with the value returned by getRefClass, and then the writeExternal method is invoked on this object's ref field passing out as the argument; otherwise, the writeUTF method is invoked on out with a zero-length string (""), and then the writeObject method is invoked on out passing this object's ref field as the argument.

Serial Data:

The serialized data for this class comprises a string (written with ObjectOutput.writeUTF) that is either the external ref type name of the contained RemoteRef instance (the ref field) or a zero-length string, followed by either the external form of the ref field as written by its writeExternal method if the string was of non-zero length, or the serialized form of the ref field as written by passing it to the serialization stream's writeObject if the string was of zero length.

If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was returned from any of the UnicastRemoteObject.exportObject methods and custom socket factories are not used, the external ref type name is "UnicastRef". If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was returned from any of the UnicastRemoteObject.exportObject methods and custom socket factories are used, the external ref type name is "UnicastRef2". If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was returned from any of the java.rmi.activation.Activatable.exportObject methods, the external ref type name is "ActivatableRef". If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was returned from the RemoteObject.toStub method (and the argument passed to toStub was not itself a RemoteStub), the external ref type name is a function of how the remote object passed to toStub was exported, as described above. If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was originally created via deserialization, the external ref type name is the same as that which was read when this object was deserialized.

If this object is an instance of java.rmi.server.UnicastRemoteObject that does not use custom socket factories, the external ref type name is "UnicastServerRef". If this object is an instance of UnicastRemoteObject that does use custom socket factories, the external ref type name is "UnicastServerRef2".

Following is the data that must be written by the writeExternal method and read by the readExternal method of RemoteRef implementation classes that correspond to the each of the defined external ref type names:

For "UnicastRef":

• the hostname of the referenced remote object, written by DataOutput.writeUTF(String)
• the port of the referenced remote object, written by DataOutput.writeInt(int)
• the data written as a result of calling {link java.rmi.server.ObjID#write(java.io.ObjectOutput)} on the ObjID instance contained in the reference
• the boolean value false, written by DataOutput.writeBoolean(boolean)

For "UnicastRef2" with a null client socket factory:

• the byte value 0x00 (indicating null client socket factory), written by DataOutput.writeByte(int)
• the hostname of the referenced remote object, written by DataOutput.writeUTF(String)
• the port of the referenced remote object, written by DataOutput.writeInt(int)
• the data written as a result of calling {link java.rmi.server.ObjID#write(java.io.ObjectOutput)} on the ObjID instance contained in the reference
• the boolean value false, written by DataOutput.writeBoolean(boolean)

For "UnicastRef2" with a non-null client socket factory:

• the byte value 0x01 (indicating non-null client socket factory), written by DataOutput.writeByte(int)
• the hostname of the referenced remote object, written by DataOutput.writeUTF(String)
• the port of the referenced remote object, written by DataOutput.writeInt(int)
• a client socket factory (object of type java.rmi.server.RMIClientSocketFactory), written by passing it to an invocation of writeObject on the stream instance
• the data written as a result of calling {link java.rmi.server.ObjID#write(java.io.ObjectOutput)} on the ObjID instance contained in the reference
• the boolean value false, written by DataOutput.writeBoolean(boolean)

For "ActivatableRef" with a null nested remote reference:

• an instance of java.rmi.activation.ActivationID, written by passing it to an invocation of writeObject on the stream instance
• a zero-length string (""), written by DataOutput.writeUTF(String)

For "ActivatableRef" with a non-null nested remote reference:

• an instance of java.rmi.activation.ActivationID, written by passing it to an invocation of writeObject on the stream instance
• the external ref type name of the nested remote reference, which must be "UnicastRef2", written by DataOutput.writeUTF(String)
• the external form of the nested remote reference, written by invoking its writeExternal method with the stream instance (see the description of the external form for "UnicastRef2" above)

For "UnicastServerRef" and "UnicastServerRef2", no data is written by the writeExternal method or read by the readExternal method.

readObject

private void readObject(ObjectInputStream stream)
                 throws IOException,
                        ClassNotFoundException

Reads the default serializable fields from the stream and performs validations and adjustments for older serialized versions. The validations and adjustments are:

1. Verify that the superclass's digit count fields correctly reflect the limits imposed on formatting numbers other than BigInteger and BigDecimal objects. These limits are stored in the superclass for serialization compatibility with older versions, while the limits for BigInteger and BigDecimal objects are kept in this class. If, in the superclass, the minimum or maximum integer digit count is larger than DOUBLE_INTEGER_DIGITS or if the minimum or maximum fraction digit count is larger than DOUBLE_FRACTION_DIGITS, then the stream data is invalid and this method throws an InvalidObjectException.
2. If serialVersionOnStream is less than 4, initialize roundingMode to RoundingMode.HALF_EVEN. This field is new with version 4.
3. If serialVersionOnStream is less than 3, then call the setters for the minimum and maximum integer and fraction digits with the values of the corresponding superclass getters to initialize the fields in this class. The fields in this class are new with version 3.
4. If serialVersionOnStream is less than 1, indicating that the stream was written by JDK 1.1, initialize useExponentialNotation to false, since it was not present in JDK 1.1.
5. Set serialVersionOnStream to the maximum allowed value so that default serialization will work properly if this object is streamed out again.

Stream versions older than 2 will not have the affix pattern variables posPrefixPattern etc. As a result, they will be initialized to null, which means the affix strings will be taken as literal values. This is exactly what we want, since that corresponds to the pre-version-2 behavior.

Reconstitutes this object from a stream (i.e., deserialize it).

Throws:

IOException

ClassNotFoundException

writeObject

private void writeObject(ObjectOutputStream stream)
                  throws IOException

Save the state of this object to a stream (i.e., serialize it). Ideally, Calendar would only write out its state data and the current time, and not write any field data out, such as fields[], isTimeSet, areFieldsSet, and isSet[]. nextStamp also should not be part of the persistent state. Unfortunately, this didn't happen before JDK 1.1 shipped. To be compatible with JDK 1.1, we will always have to write out the field values and state flags. However, nextStamp can be removed from the serialization stream; this will probably happen in the near future.

Throws:

IOException

Serialized Fields

areFieldsSet

boolean areFieldsSet

True if fields[] are in sync with the currently set time. If false, then the next attempt to get the value of a field will force a recomputation of all fields from the current value of time.

fields

int[] fields

The calendar field values for the currently set time for this calendar. This is an array of FIELD_COUNT integers, with index values ERA through DST_OFFSET.

firstDayOfWeek

int firstDayOfWeek

The first day of the week, with possible values SUNDAY, MONDAY, etc. This is a locale-dependent value.

isSet

boolean[] isSet

The flags which tell if a specified calendar field for the calendar is set. A new object has no fields set. After the first call to a method which generates the fields, they all remain set after that. This is an array of FIELD_COUNT booleans, with index values ERA through DST_OFFSET.

isTimeSet

boolean isTimeSet

True if then the value of time is valid. The time is made invalid by a change to an item of field[].

See Also:

Calendar.time

lenient

boolean lenient

True if this calendar allows out-of-range field values during computation of time from fields[].

See Also:

Calendar.setLenient(boolean), Calendar.isLenient()

minimalDaysInFirstWeek

int minimalDaysInFirstWeek

The number of days required for the first week in a month or year, with possible values from 1 to 7. This is a locale-dependent value.

nextStamp

int nextStamp

The next available value for stamp[], an internal array. This actually should not be written out to the stream, and will probably be removed from the stream in the near future. In the meantime, a value of MINIMUM_USER_STAMP should be used.

serialVersionOnStream

int serialVersionOnStream

The version of the serialized data on the stream. Possible values:

0 or not present on stream

JDK 1.1.5 or earlier.

1

JDK 1.1.6 or later. Writes a correct 'time' value as well as compatible values for other fields. This is a transitional format.

When streaming out this class, the most recent format and the highest allowable serialVersionOnStream is written.

Since:

1.1.6

time

long time

The currently set time for this calendar, expressed in milliseconds after January 1, 1970, 0:00:00 GMT.

See Also:

Calendar.isTimeSet

zone

TimeZone zone

The TimeZone used by this calendar. Calendar uses the time zone data to translate between locale and GMT time.

private void readObject(ObjectInputStream ois)

Reads objects from the stream and stores them in the transient Object[] array field.

Serial Data:

A nonnegative int, indicating the count of objects, followed by that many objects.

Throws:

IOException - if an I/O error occurs

ClassNotFoundException - if a serialized class cannot be loaded

InvalidObjectException - if the count is negative

Since:

readResolve

private Object readResolve()

Creates and returns an immutable collection from this proxy class. The instance returned is created as if by calling one of the static factory methods for List, Map, or Set. This proxy class is the serial form for all immutable collection instances, regardless of implementation type. This is necessary to ensure that the existence of any particular implementation type is kept out of the serialized form.

Throws:

Serialized Fields

tag

int tag

Indicates the type of collection that is serialized. The low order 8 bits have the value 1 for an immutable List, 2 for an immutable Set, and 3 for an immutable Map. Any other value causes an InvalidObjectException to be thrown. The high order 24 bits are zero when an instance is serialized, and they are ignored when an instance is deserialized. They can thus be used by future implementations without causing compatibility issues.

The tag value also determines the interpretation of the transient Object[] array field. For List and Set, the array's length is the size of the collection, and the array contains the elements of the collection. Null elements are not allowed. For Set, duplicate elements are not allowed.

For Map, the array's length is twice the number of mappings present in the map. The array length is necessarily even. The array contains a succession of key and value pairs: k1, v1, k2, v2, ..., kN, vN. Nulls are not allowed, and duplicate keys are not allowed.

private void readObject(ObjectInputStream stream)
                 throws IOException,
                        ClassNotFoundException

Reconstitute this object from a stream (i.e., deserialize it). We handle both JDK 1.1 binary formats and full formats with a packed byte array.

Throws:

IOException

ClassNotFoundException

writeObject

private void writeObject(ObjectOutputStream stream)
                  throws IOException

Save the state of this object to a stream (i.e., serialize it).

Serial Data:

We write out two formats, a JDK 1.1 compatible format, using DOW_IN_MONTH_MODE rules, in the required section, followed by the full rules, in packed format, in the optional section. The optional section will be ignored by JDK 1.1 code upon stream in.

Contents of the optional section: The length of a byte array is emitted (int); this is 4 as of this release. The byte array of the given length is emitted. The contents of the byte array are the true values of the fields startDay, startDayOfWeek, endDay, and endDayOfWeek. The values of these fields in the required section are approximate values suited to the rule mode DOW_IN_MONTH_MODE, which is the only mode recognized by JDK 1.1.

Throws:

IOException

Serialized Fields

dstSavings

int dstSavings

A positive value indicating the amount of time saved during DST in milliseconds. Typically one hour (3600000); sometimes 30 minutes (1800000).

If useDaylight is false, this value is ignored.

Since:

1.1.4

endDay

int endDay

This field has two possible interpretations:

endMode == DOW_IN_MONTH

endDay indicates the day of the month of endMonth on which daylight saving time ends, from 1 to 28, 30, or 31, depending on the endMonth.

endMode != DOW_IN_MONTH

endDay indicates which endDayOfWeek in th month endMonth daylight saving time ends on. For example, a value of +1 and a endDayOfWeek of Calendar.SUNDAY indicates the first Sunday of endMonth. Likewise, +2 would indicate the second Sunday, and -1 the last Sunday. A value of 0 is illegal.

If useDaylight is false, this value is ignored.

endDayOfWeek

int endDayOfWeek

The day of the week on which daylight saving time ends. This value must be between Calendar.SUNDAY and Calendar.SATURDAY inclusive.

If useDaylight is false or endMode == DAY_OF_MONTH, this value is ignored.

endMode

int endMode

Variables specifying the mode of the end rule. Takes the following values:

DOM_MODE

Exact day of week; e.g., March 1.

DOW_IN_MONTH_MODE

Day of week in month; e.g., last Sunday in March.

DOW_GE_DOM_MODE

Day of week after day of month; e.g., Sunday on or after March 15.

DOW_LE_DOM_MODE

Day of week before day of month; e.g., Sunday on or before March 15.

The setting of this field affects the interpretation of the endDay field.

If useDaylight is false, this value is ignored.

Since:

1.1.4

endMonth

int endMonth

The month in which daylight saving time ends. This value must be between Calendar.JANUARY and Calendar.UNDECIMBER. This value must not equal startMonth.

If useDaylight is false, this value is ignored.

endTime

int endTime

The time in milliseconds after midnight at which daylight saving time ends. This value is expressed as wall time, standard time, or UTC time, depending on the setting of endTimeMode.

If useDaylight is false, this value is ignored.

endTimeMode

int endTimeMode

The format of endTime, either WALL_TIME, STANDARD_TIME, or UTC_TIME.

Since:

1.3

monthLength

byte[] monthLength

This field was serialized in JDK 1.1, so we have to keep it that way to maintain serialization compatibility. However, there's no need to recreate the array each time we create a new time zone.

An array of bytes containing the values {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}. This is ignored as of the Java 2 platform v1.2, however, it must be streamed out for compatibility with JDK 1.1.

rawOffset

int rawOffset

The offset in milliseconds between this zone and GMT. Negative offsets are to the west of Greenwich. To obtain local standard time, add the offset to GMT time. To obtain local wall time it may also be necessary to add dstSavings.

serialVersionOnStream

int serialVersionOnStream

The version of the serialized data on the stream. Possible values:

0 or not present on stream

JDK 1.1.3 or earlier.

1

JDK 1.1.4 or later. Includes three new fields: startMode, endMode, and dstSavings.

2

JDK 1.3 or later. Includes two new fields: startTimeMode and endTimeMode.

When streaming out this class, the most recent format and the highest allowable serialVersionOnStream is written.

Since:

1.1.4

startDay

int startDay

This field has two possible interpretations:

startMode == DOW_IN_MONTH

startDay indicates the day of the month of startMonth on which daylight saving time starts, from 1 to 28, 30, or 31, depending on the startMonth.

startMode != DOW_IN_MONTH

startDay indicates which startDayOfWeek in the month startMonth daylight saving time starts on. For example, a value of +1 and a startDayOfWeek of Calendar.SUNDAY indicates the first Sunday of startMonth. Likewise, +2 would indicate the second Sunday, and -1 the last Sunday. A value of 0 is illegal.

If useDaylight is false, this value is ignored.

startDayOfWeek

int startDayOfWeek

The day of the week on which daylight saving time starts. This value must be between Calendar.SUNDAY and Calendar.SATURDAY inclusive.

If useDaylight is false or startMode == DAY_OF_MONTH, this value is ignored.

startMode

int startMode

Variables specifying the mode of the start rule. Takes the following values:

DOM_MODE

Exact day of week; e.g., March 1.

DOW_IN_MONTH_MODE

Day of week in month; e.g., last Sunday in March.

DOW_GE_DOM_MODE

Day of week after day of month; e.g., Sunday on or after March 15.

DOW_LE_DOM_MODE

Day of week before day of month; e.g., Sunday on or before March 15.

The setting of this field affects the interpretation of the startDay field.

If useDaylight is false, this value is ignored.

Since:

1.1.4

startMonth

int startMonth

The month in which daylight saving time starts. This value must be between Calendar.JANUARY and Calendar.DECEMBER inclusive. This value must not equal endMonth.

If useDaylight is false, this value is ignored.

startTime

int startTime

The time in milliseconds after midnight at which daylight saving time starts. This value is expressed as wall time, standard time, or UTC time, depending on the setting of startTimeMode.

If useDaylight is false, this value is ignored.

startTimeMode

int startTimeMode

The format of startTime, either WALL_TIME, STANDARD_TIME, or UTC_TIME.

Since:

1.3

startYear

int startYear

The year in which daylight saving time is first observed. This is an AD value. If this value is less than 1 then daylight saving time is observed for all AD years.

If useDaylight is false, this value is ignored.

useDaylight

boolean useDaylight

A boolean value which is true if and only if this zone uses daylight saving time. If this value is false, several other fields are ignored.

The status field holds run control status bits packed into a single int to ensure atomicity. Status is initially zero, and takes on nonnegative values until completed, upon which it holds (sign bit) DONE, possibly with ABNORMAL (cancelled or exceptional) and THROWN (in which case an exception has been stored). Tasks with dependent blocked waiting joiners have the SIGNAL bit set. Completion of a task with SIGNAL set awakens any waiters via notifyAll. (Waiters also help signal others upon completion.) These control bits occupy only (some of) the upper half (16 bits) of status field. The lower bits are used for user-defined tags.
