All Implemented Interfaces:

CoreActivityBehavior<ActivityExecution>, ActivityBehavior, SignallableActivityBehavior

public class ClassDelegateActivityBehavior
extends AbstractBpmnActivityBehavior

Helper class for bpmn constructs that allow class delegation. This class will lazily instantiate the referenced classes when needed at runtime.
