Method Summary

protected List<ActivityExecution>	createConcurrentExecutions(ActivityExecution execution, int nrOfInstances)
protected void	createInstances(ActivityExecution execution, int nrOfInstances) Handles the parallel case of spawning the instances.

Constructor Detail

ParallelMultiInstanceBehavior

public ParallelMultiInstanceBehavior(ActivityImpl activity,
                                     AbstractBpmnActivityBehavior originalActivityBehavior)

Method Detail

createInstances

protected void createInstances(ActivityExecution execution,
                               int nrOfInstances)
                        throws Exception

Handles the parallel case of spawning the instances. Will create child executions accordingly for every instance needed.

Specified by:

createInstances in class MultiInstanceActivityBehavior

Throws:

Exception

doExecuteOriginalBehavior

protected void doExecuteOriginalBehavior(ActivityExecution execution,
                                         int loopCounter)
                                  throws Exception

Description copied from class: MultiInstanceActivityBehavior

Subclasses get the chance to adapt their behavior according to the current loop counter.

Specified by:

doExecuteOriginalBehavior in class MultiInstanceActivityBehavior

Throws:

Exception

createConcurrentExecutions

protected List<ActivityExecution> createConcurrentExecutions(ActivityExecution execution,
                                                             int nrOfInstances)

createTimerJobsForExecution

protected void createTimerJobsForExecution(ActivityExecution execution)

leave

public void leave(ActivityExecution execution)

Called when the wrapped ActivityBehavior calls the AbstractBpmnActivityBehavior.leave(ActivityExecution) method. Handles the completion of one of the parallel instances

Overrides:

leave in class FlowNodeActivityBehavior

fixMiRootActivityInstanceId

protected void fixMiRootActivityInstanceId(ActivityExecution execution)

resetMiRootActivityInstanceId

protected void resetMiRootActivityInstanceId(ActivityExecution execution)
