Method Details

createInstances

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

Specified by:

createInstances in class MultiInstanceActivityBehavior

Throws:

Exception

complete

public void complete(ActivityExecution scopeExecution)

concurrentChildExecutionEnded

public void concurrentChildExecutionEnded(ActivityExecution scopeExecution,
 ActivityExecution endedExecution)

Description copied from interface: CompositeActivityBehavior

Invoked when an execution is ended within the scope of the composite

Parameters:

scopeExecution - scope execution for the activity which defined the behavior

endedExecution - the execution which ended

prepareScope

protected void prepareScope(ActivityExecution scopeExecution,
 int totalNumberOfInstances)

initializeScope

public List<ActivityExecution> initializeScope(ActivityExecution scopeExecution,
 int nrOfInstances)

Description copied from interface: ModificationObserverBehavior

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

public ActivityExecution createInnerInstance(ActivityExecution scopeExecution)

Description copied from interface: ModificationObserverBehavior

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

public void destroyInnerInstance(ActivityExecution scopeExecution)

Description copied from interface: ModificationObserverBehavior

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.
