Interface HandlerChain

All Superinterfaces:: Collection, List

public interface HandlerChain
extends List

This interface represents a list of handlers. All elements in the HandlerChain are of the type javax.xml.rpc.handler.Handler. An implementation class for the HandlerChain interface abstracts the policy and mechanism for the invocation of the registered handlers.

Method Summary

void destroy()
          Indicates the end of lifecycle for a HandlerChain.

String[] getRoles()

boolean handleFault(MessageContext msgContext)
          The handleFault method initiates the SOAP fault processing for this handler chain.

boolean handleRequest(MessageContext msgContext)
          The handleRequest method initiates the request processing for this handler chain.

boolean handleResponse(MessageContext msgContext)
          The handleResponse method initiates the response processing for this handler chain.

void init(Map config)

Method Detail

init

public void init(Map config)

Initializes the configuration for a HandlerChain.

Parameters:: config - Configuration for the initialization of this handler chain
Throws:: JAXRPCException - If any error during initialization

destroy

public void destroy()

Indicates the end of lifecycle for a HandlerChain.

Throws:: JAXRPCException - If any error during destroy

getRoles

public String[] getRoles()

Gets SOAP actor roles registered for this HandlerChain at this SOAP node. The returned array includes the special SOAP actor next.

Returns:: SOAP Actor roles as URIs

setRoles

public void setRoles(String[] soapActorNames)

Sets SOAP Actor roles for this HandlerChain. This specifies the set of roles in which this HandlerChain is to act for the SOAP message processing at this SOAP node. These roles assumed by a HandlerChain must be invariant during the processing of an individual SOAP message through the HandlerChain.

A HandlerChain always acts in the role of the special SOAP actor next. Refer to the SOAP specification for the URI name for this special SOAP actor. There is no need to set this special role using this method.

Parameters:: soapActorNames - URIs for SOAP actor name

handleRequest

public boolean handleRequest(MessageContext msgContext)

The handleRequest method initiates the request processing for this handler chain.

Parameters:: msgContext - MessageContext parameter provides access to the request SOAP message.
Returns:: Returns true if all handlers in chain have been processed. Returns false if a handler in the chain returned false from its handleRequest method.
Throws:: JAXRPCException - if any processing error happens

handleResponse

public boolean handleResponse(MessageContext msgContext)

The handleResponse method initiates the response processing for this handler chain.

Returns:: Returns true if all handlers in chain have been processed. Returns false if a handler in the chain returned false from its handleRequest method.
Throws:: JAXRPCException - if any processing error happens

handleFault

public boolean handleFault(MessageContext msgContext)

The handleFault method initiates the SOAP fault processing for this handler chain.

Returns:: Returns true if all handlers in chain have been processed. Returns false if a handler in the chain returned false from its handleRequest method.
Throws:: JAXRPCException - if any processing error happens
