Method Detail

execute

void execute(ActivityExecution execution)
             throws java.lang.Exception

piece of Java code that is to be included in a process as activity behaviour or as a hidden listener to process events.

ActivityBehaviour's can be used to implement the behaviour of activities, in which case this behaviour is associated to a graphical activity in the diagram.

An ActivityBehaviour can control the propagation of execution. ActivityBehaviour's can become external activities when they invoke ActivityExecution.waitForSignal(). That means the activity will become a wait state. In that case, ExternalActivityBehaviour should be implemented to also handle the external triggers.

Throws:

java.lang.Exception
