Constructor Detail

FaultableHandler

public FaultableHandler(Handler workHandler)

Constructor
Parameters:: workHandler - the Handler we're going to wrap with Fault semantics.

Method Detail

init

public void init()

Description copied from class: BasicHandler

Stubbed-out methods. Override in your child class to implement any real behavior.

Specified by:: init in interface Handler
Overrides:: init in class BasicHandler

cleanup

public void cleanup()

Description copied from interface: Handler

Cleanup is called when the chain containing this Handler object is done processing the chain.

Specified by:: cleanup in interface Handler
Overrides:: cleanup in class BasicHandler

invoke

public void invoke(MessageContext msgContext)
            throws AxisFault

Invokes the specified handler. If there's a fault the appropriate key will be calculated and used to find the fault chain to be invoked. This assumes that the workHandler has caught the exception and already done its fault processing - as needed.

Specified by:: invoke in interface Handler
Specified by:: invoke in class BasicHandler

Throws:: AxisFault

onFault

public void onFault(MessageContext msgContext)

Some handler later on has faulted so we need to process the fault.

Specified by:: onFault in interface Handler
Overrides:: onFault in class BasicHandler

canHandleBlock

public boolean canHandleBlock(javax.xml.namespace.QName qname)
