Class DelegateExpressionFlowableEventListener

java.lang.Object

org.flowable.common.engine.api.delegate.event.AbstractFlowableEventListener

org.flowable.engine.impl.bpmn.helper.BaseDelegateEventListener

org.flowable.engine.impl.bpmn.helper.DelegateExpressionFlowableEventListener

All Implemented Interfaces:

FlowableEventListener

public class DelegateExpressionFlowableEventListener
extends BaseDelegateEventListener

An FlowableEventListener implementation which resolves an expression to a delegate FlowableEventListener instance and uses this for event notification.

In case an entityClass was passed in the constructor, only events that are FlowableEntityEvent's that target an entity of the given type, are dispatched to the delegate.
