Class FlowNodeActivityBehavior

java.lang.Object

org.activiti.engine.impl.bpmn.behavior.FlowNodeActivityBehavior

All Implemented Interfaces:

Serializable, ActivityBehavior, SignallableActivityBehavior

Direct Known Subclasses:

AbstractBpmnActivityBehavior, BoundaryEventActivityBehavior, CancelBoundaryEventActivityBehavior, CancelEndEventActivityBehavior, ErrorEndEventActivityBehavior, EventBasedGatewayActivityBehavior, GatewayActivityBehavior, IntermediateThrowCompensationEventActivityBehavior, IntermediateThrowNoneEventActivityBehavior, MultiInstanceActivityBehavior, NoneEndEventActivityBehavior, NoneStartEventActivityBehavior, TerminateEndEventActivityBehavior

public abstract class FlowNodeActivityBehavior
extends Object
implements SignallableActivityBehavior

Superclass for all 'connectable' BPMN 2.0 process elements: tasks, gateways and events. This means that any subclass can be the source or target of a sequenceflow. Corresponds with the notion of the 'flownode' in BPMN 2.0.
