Method Detail

process

public MuleEvent process(MuleEvent event)
                  throws MuleException

This final process implementation shields actual processing into abstract method doProcess(org.mule.api.MuleEvent). Afterwards, it performs payload transformation by invoking overwritePayload(org.mule.api.MuleEvent, Object) In case the processing throws NotAuthorizedException, the module object is casted to OAuthAdapter and exception handling is delegated into its OnNoTokenPolicy. For any other kind of exception, it is logged and wrapped into a MuleException

Parameters:

event - the current mule event.

Returns:

the mule event returned by the message processor or the OnNoTokenPolicy in case of NotAuthorizedException

Throws:

MuleException

doProcess

protected abstract MuleEvent doProcess(MuleEvent event)
                                throws Exception

Implementors of this class need to implement this method in order to perform actual processing

Parameters:

event - the mule event

Returns:

a mule event

Throws:

Exception

findOrCreate

protected final Object findOrCreate(Class<?> moduleClass,
                  boolean shouldAutoCreate,
                  MuleEvent muleEvent)
                             throws IllegalAccessException,
                                    InstantiationException,
                                    ConfigurationException,
                                    RegistrationException

Obtains the expression manager from the Mule context and initialises the connector. If a target object has not been set already it will search the Mule registry for a default one.

Throws:

InstantiationException

ConfigurationException

IllegalAccessException

RegistrationException

overwritePayload

public final void overwritePayload(MuleEvent event,
                    Object resultPayload)
                            throws Exception

Overwrites the event payload with the specified one

Throws:

Exception

initialise

public void initialise()
                throws InitialisationException

Obtains the expression manager from the Mule context and initialises the connector. If a target object has not been set already it will search the Mule registry for a default one.

Specified by:

initialise in interface Initialisable

Throws:

InitialisationException

start

public void start()
           throws MuleException

Specified by:

start in interface Startable

Throws:

MuleException

stop

public void stop()
          throws MuleException

Specified by:

stop in interface Stoppable

Throws:

MuleException

dispose

public void dispose()

Specified by:

dispose in interface Disposable
