Constructor Detail

ParallelMultiInstanceActivityBehavior

public ParallelMultiInstanceActivityBehavior()

Method Detail

createInstances

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

Specified by:

createInstances in class MultiInstanceActivityBehavior

Throws:

Exception

prepareScopeExecution

protected void prepareScopeExecution(ActivityExecution scopeExecution,
                                     int nrOfInstances)

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

allExecutionsEnded

protected boolean allExecutionsEnded(ActivityExecution scopeExecution,
                                     ActivityExecution endedExecution)

complete

public void complete(ActivityExecution scopeExecution)

initializeScope

public ActivityExecution initializeScope(ActivityExecution scopeExecution)

Description copied from interface: ModificationObserverBehavior

Implement to customize the creation of executions in the scope. Called with the scope execution already created for this scope, implementations may create additional execution, set variables, etc. (cf. parallel multi instance that always creates a concurrent execution, although there is only one instance)

concurrentExecutionCreated

public void concurrentExecutionCreated(ActivityExecution scopeExecution,
                                       ActivityExecution concurrentExecution)

Description copied from interface: ModificationObserverBehavior

implement to handle reorganization of the scope when a concurrent execution in the scope is created (e.g. implement to override the default pruning behavior)

concurrentExecutionDeleted

public void concurrentExecutionDeleted(ActivityExecution scopeExecution,
                                       ActivityExecution concurrentExecution)

Description copied from interface: ModificationObserverBehavior

implement to handle reorganization of the scope when a concurrent execution in the scope is removed (e.g. implement to override the default pruning behavior)
