ListenerHolder (Jetty :: Project 9.4.56.v20240826 API)

java.lang.Object
- org.eclipse.jetty.util.component.AbstractLifeCycle
- - org.eclipse.jetty.servlet.BaseHolder<java.util.EventListener>
  - - org.eclipse.jetty.servlet.ListenerHolder

All Implemented Interfaces:

Dumpable, LifeCycle
```
public class ListenerHolder
extends BaseHolder<java.util.EventListener>
```
ListenerHolder Specialization of BaseHolder for servlet listeners. This allows us to record where the listener originated - web.xml, annotation, api etc.

    Set an explicit instance. In this case, just like ServletHolder and FilterHolder, the listener will not be introspected for annotations like Resource etc.

    doStart in class BaseHolder<java.util.EventListener>
    
    Throws:
