Class TakeOutgoingSequenceFlowsOperation

java.lang.Object

org.flowable.engine.impl.agenda.AbstractOperation

org.flowable.engine.impl.agenda.TakeOutgoingSequenceFlowsOperation

All Implemented Interfaces:

Runnable

public class TakeOutgoingSequenceFlowsOperation
extends AbstractOperation

Operation which purpose is to leave a FlowNode. This can be done by setting either the FlowNode or selecting a particular SequenceFlow: - when the execution currently is at a FlowNode, leaves it by following the outgoing sequence flow, evaluating conditions if necessary. - when the execution currently is at a SequenceFlow, this sequence flow will be followed. Any condition is ignored, as the assumed use case for this situation is a custom ActivityBehavior (such as a gateway) that has non-default behavior of leaving the FlowNode by checking conditions on all sequence flow and taking those which evaluate to true.
