Method Detail

process

public MuleEvent process(MuleEvent event)
                  throws MuleException

Description copied from interface: Interceptor

Invoked when the component should be called. The implementation can call next.process(event) to call the component or the next filer in the chain.

Specified by:

process in interface Interceptor

Specified by:

process in interface MessageProcessor

Parameters:

event - the event containing info about the current message and service

Returns:

A result message that may have been altered by this invocation

Throws:

MuleException

getInterceptors

public List<Interceptor> getInterceptors()

setInterceptors

public void setInterceptors(List<Interceptor> interceptors)

initialise

public void initialise()
                throws InitialisationException

Description copied from interface: Initialisable

Method used to perform any initialisation work. If a fatal error occurs during initialisation an InitialisationException should be thrown, causing the Mule instance to shutdown. If the error is recoverable, say by retrying to connect, a RecoverableException should be thrown. There is no guarantee that by throwing a Recoverable exception that the Mule instance will not shut down.

Specified by:

initialise in interface Initialisable

Throws:

InitialisationException - if a fatal error occurs causing the Mule instance to shutdown

RecoverableException - if an error occurs that can be recovered from

dispose

public void dispose()

Description copied from interface: Disposable

A lifecycle method where implementor should free up any resources. If an exception is thrown it should just be logged and processing should continue. This method should not throw Runtime exceptions.

Specified by:

dispose in interface Disposable

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
