Method Details

doLeave

public void doLeave(ActivityExecution execution)

Subclasses that call leave() will first pass through this method, before the regular FlowNodeActivityBehavior.leave(ActivityExecution) is called.

Overrides:

doLeave in class FlowNodeActivityBehavior

isCompensationEventSubprocess

protected boolean isCompensationEventSubprocess(ActivityImpl activity)

createCompensateEventSubscription

protected void createCompensateEventSubscription(ActivityExecution execution,
 ActivityImpl compensationHandler)

executeWithErrorPropagation

protected void executeWithErrorPropagation(ActivityExecution execution,
 Callable<Void> toExecute)
                                    throws Exception

Takes an ActivityExecution and an Callable and wraps the call to the Callable with the proper error propagation. This method also makes sure that exceptions not caught by following activities in the process will be thrown and not propagated.

Parameters:

execution -

toExecute -

Throws:

Exception

signal

public void signal(ActivityExecution execution,
 String signalName,
 Object signalData)
            throws Exception

Specified by:

signal in interface SignallableActivityBehavior

Overrides:

signal in class FlowNodeActivityBehavior

Throws:

Exception

signalCompensationDone

protected void signalCompensationDone(ActivityExecution execution)
