javax.xml.rpc.handler
Class GenericHandler

java.lang.Object
  extended by javax.xml.rpc.handler.GenericHandler
All Implemented Interfaces:
Handler

public abstract class GenericHandler
extends Object
implements Handler

The javax.xml.rpc.handler.GenericHandler class implements the Handler interface. SOAP Message Handler developers should typically subclass GenericHandler class unless the Handler class needs another class as a superclass.

The GenericHandler class is a convenience abstract class that makes writing Handlers easy. This class provides default implementations of the lifecycle methods init and destroy and also different handle methods. A Handler developer should only override methods that it needs to specialize as part of the derived Handler implementation class.

Version:
1.0

Method Detail

handleRequest

public boolean handleRequest(MessageContext context)
The handleRequest method processes the request SOAP message. The default implementation of this method returns true. This indicates that the handler chain should continue processing of the request SOAP message. This method should be overridden if the derived Handler class needs to specialize implementation of this method.

Specified by:
handleRequest in interface Handler
Parameters:
context - the message context
Returns:
true/false

handleResponse

public boolean handleResponse(MessageContext context)
The handleResponse method processes the response message. The default implementation of this method returns true. This indicates that the handler chain should continue processing of the response SOAP message. This method should be overridden if the derived Handler class needs to specialize implementation of this method.

Specified by:
handleResponse in interface Handler
Parameters:
context - the message context
Returns:
true/false

handleFault

public boolean handleFault(MessageContext context)
The handleFault method processes the SOAP faults based on the SOAP message processing model. The default implementation of this method returns true. This indicates that the handler chain should continue processing of the SOAP fault. This method should be overridden if the derived Handler class needs to specialize implementation of this method.

Specified by:
handleFault in interface Handler
Parameters:
context - the message context
Returns:
true/false

init

public void init(HandlerInfo config)
The init method to enable the Handler instance to initialize itself. This method should be overridden if the derived Handler class needs to specialize implementation of this method.

Specified by:
init in interface Handler
Parameters:
config - handler configuration

destroy

public void destroy()
The destroy method indicates the end of lifecycle for a Handler instance. This method should be overridden if the derived Handler class needs to specialize implementation of this method.

Specified by:
destroy in interface Handler

getHeaders

public abstract QName[] getHeaders()
Gets the header blocks processed by this Handler instance.

Specified by:
getHeaders in interface Handler
Returns:
Array of QNames of header blocks processed by this handler instance. QName is the qualified name of the outermost element of the Header block.
