Methods

Modifier and Type	Method and Description
protected void	createInstances(ActivityExecution execution, int nrOfInstances) Handles the sequential case of spawning the instances.
void	execute(ActivityExecution execution) Default behaviour: just leave the activity with no extra functionality.
void	leave(ActivityExecution execution) Called when the wrapped ActivityBehavior calls the AbstractBpmnActivityBehavior.leave(ActivityExecution) method.

SequentialMultiInstanceBehavior

public SequentialMultiInstanceBehavior(ActivityImpl activity,
                               AbstractBpmnActivityBehavior innerActivityBehavior)

Method Detail

createInstances

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

Handles the sequential case of spawning the instances. Will only create one instance, since at most one instance can be active.

Specified by:

createInstances in class MultiInstanceActivityBehavior

Throws:

Exception

leave

public void leave(ActivityExecution execution)

Called when the wrapped ActivityBehavior calls the AbstractBpmnActivityBehavior.leave(ActivityExecution) method. Handles the completion of one instance, and executes the logic for the sequential behavior.

Overrides:

leave in class FlowNodeActivityBehavior

execute

public void execute(ActivityExecution execution)
             throws Exception

Description copied from class: FlowNodeActivityBehavior

Default behaviour: just leave the activity with no extra functionality.

Specified by:

execute in interface ActivityBehavior

Overrides:

execute in class MultiInstanceActivityBehavior

Throws:

Exception
