Class org.jbpm.api.activity.ActivityBehaviour

Examples of org.jbpm.api.activity.ActivityBehaviour.execute()

org.jbpm.api.activity.ActivityBehaviour.execute()
invoked when an execution arrives in an activity.
An ActivityBehaviour can control the propagation of execution. ActivityBehaviour's can become external activities when they invoke {@link ActivityExecution#waitForSignal()}. That means the activity will become a wait state. In that case, {@link ExternalActivityBehaviour} should be implemented to also handle the external signals.

    
    try {
      execution.setPropagation(Propagation.UNSPECIFIED);
      execution.setHistoryActivityStart(Clock.getCurrentTime());


      activityBehaviour.execute(execution);
      
    } catch (Exception e) {
      execution.handleException(activity, null, null, e, execution.toString()+" couldn't execute "+activityBehaviour+" for activity "+activity);
    }
