public abstract class MultiInstanceActivityBehavior
- extends FlowNodeActivityBehavior
- implements CompositeActivityBehavior, SubProcessActivityBehavior
Implementation of the multi-instance functionality as described in the BPMN 2.0 spec.
Multi instance functionality is implemented as an ActivityBehavior
that
wraps the original ActivityBehavior
of the activity.
Only subclasses of AbstractBpmnActivityBehavior
can have multi-instance
behavior. As such, special logic is contained in the AbstractBpmnActivityBehavior
to delegate to the MultiInstanceActivityBehavior
if needed.

方法摘要 |
protected void |
callActivityEndListeners(ActivityExecution execution)
Since no transitions are followed when leaving the inner activity,
it is needed to call the end listeners yourself. |
void |
completed(ActivityExecution execution)
called after the process instance is destroyed for
this activity to perform its outgoing control flow logic. |
void |
completing(DelegateExecution execution,
DelegateExecution subProcessInstance)
called before the process instance is destroyed to allow
this activity to extract data from the sub process instance. |
protected boolean |

protected abstract void |
createInstances(ActivityExecution execution)

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