Interface ModificationObserverBehavior
- All Superinterfaces:
ActivityBehavior
,CoreActivityBehavior<ActivityExecution>
- All Known Implementing Classes:
MultiInstanceActivityBehavior
,ParallelMultiInstanceActivityBehavior
,SequentialMultiInstanceActivityBehavior
When a (scope) activity behavior implements this behavior,
its scope execution is notified in case of an external modification about the following:
- the scope execution is newly created
- a new concurrent execution is created in that scope
- a concurrent execution is removed in that scope

(ActivityExecution scopeExecution) Returns an execution that can be used to execute an activity within that scope.void

Method Details
-
initializeScope
Implement to customize initialization of the scope. Called with the scope execution already created. Implementations may set variables, etc. Implementations should provide return as many executions as there are requested by the argument. Valid number of instances are >= 0. -
createInnerInstance
Returns an execution that can be used to execute an activity within that scope. May reorganize other executions in that scope (e.g. implement to override the default pruning behavior). -
destroyInnerInstance
implement to destroy an execution in this scope and handle the scope's reorganization (e.g. implement to override the default pruning behavior). The argument execution is not yet removed.
