DelegateExpressionFlowableEventListener (Flowable - Engine 6.8.1 API)

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.
