FileItemStream (Apache Tomcat 8.0.15 API Documentation)

All Superinterfaces:

FileItemHeadersSupport
```
public interface FileItemStream
extends FileItemHeadersSupport
```
This interface provides access to a file or form item that was received within a multipart/form-data POST request. The items contents are retrieved by calling openStream().

Instances of this class are created by accessing the iterator, returned by FileUploadBase.getItemIterator(RequestContext).

Note: There is an interaction between the iterator and its associated instances of FileItemStream: By invoking Iterator.hasNext() on the iterator, you discard all data, which hasn't been read so far from the previous data.

Nested Class Summary

Nested Classes
Modifier and Type	Interface and Description
`static class`	`FileItemStream.ItemSkippedException` This exception is thrown, if an attempt is made to read data from the `InputStream`, which has been returned by `openStream()`, after `Iterator.hasNext()` has been invoked on the iterator, which created the `FileItemStream`.

Method Summary

Methods
Modifier and Type	Method and Description
`String`	`getContentType()` Returns the content type passed by the browser or `null` if not defined.
`String`	`getFieldName()` Returns the name of the field in the multipart form corresponding to this file item.
`String`	`getName()` Returns the original filename in the client's filesystem, as provided by the browser (or other client software).
`boolean`	`isFormField()` Determines whether or not a `FileItem` instance represents a simple form field.
`InputStream`	`openStream()` Creates an `InputStream`, which allows to read the items contents.
