Class AbstractAjpProtocol<S>

java.lang.Object

org.apache.coyote.AbstractProtocol<S>

org.apache.coyote.ajp.AbstractAjpProtocol<S>

Type Parameters:

S - The type of socket used by the implementation

All Implemented Interfaces:

MBeanRegistration, ProtocolHandler

Direct Known Subclasses:

AjpAprProtocol, AjpNio2Protocol, AjpNioProtocol

public abstract class AbstractAjpProtocol<S>
extends AbstractProtocol<S>

The is the base implementation for the AJP protocol handlers. Implementations typically extend this base class rather than implement ProtocolHandler. All of the implementations that ship with Tomcat are implemented this way.

Field Detail

sm

protected static final StringManager sm

The string manager for this package.

ajpFlush

protected boolean ajpFlush

Send AJP flush packet when flushing. An flush packet is a zero byte AJP13 SEND_BODY_CHUNK packet. mod_jk and mod_proxy_ajp interprete this as a request to flush data to the client. AJP always does flush at the and of the response, so if it is not important, that the packets get streamed up to the client, do not use extra flush packets. For compatibility and to stay on the safe side, flush packets are enabled by default.

Constructor Detail

AbstractAjpProtocol

public AbstractAjpProtocol(AbstractEndpoint<S> endpoint)

Method Detail

getProtocolName

protected String getProtocolName()

Description copied from class: AbstractProtocol

Obtain the name of the protocol, (Http, Ajp, etc.). Used with JMX.

Specified by:

getProtocolName in class AbstractProtocol<S>

Returns:

the protocol name

getEndpoint

protected AbstractEndpoint<S> getEndpoint()

Overridden to make getter accessible to other classes in this package.

Overrides:

getEndpoint in class AbstractProtocol<S>

getNegotiatedProtocol

protected UpgradeProtocol getNegotiatedProtocol(String name)

Find a suitable handler for the protocol negotiated at the network layer. AJP does not support protocol negotiation so this always returns null.

Specified by:

getNegotiatedProtocol in class AbstractProtocol<S>

Parameters:

name - The name of the requested negotiated protocol.

Returns:

The instance where UpgradeProtocol.getAlpnName() matches the requested protocol

getUpgradeProtocol

protected UpgradeProtocol getUpgradeProtocol(String name)

Find a suitable handler for the protocol upgraded name specified. This is used for direct connection protocol selection. AJP does not support protocol upgrade so this always returns null.

Specified by:

getUpgradeProtocol in class AbstractProtocol<S>

Parameters:

name - The name of the requested negotiated protocol.

Returns:

The instance where UpgradeProtocol.getAlpnName() matches the requested protocol

createProcessor

protected Processor createProcessor()

Description copied from class: AbstractProtocol

Create and configure a new Processor instance for the current protocol implementation.

Specified by:

Returns:

A fully configured Processor instance that is ready to use
