RenderPerformanceListener (Wicket Parent 9.19.0-SNAPSHOT API)

java.lang.Object
- org.apache.wicket.devutils.inspector.RenderPerformanceListener

All Implemented Interfaces:

IComponentInstantiationListener
```
public class RenderPerformanceListener
extends Object
implements IComponentInstantiationListener
```
A listener that adds a special Behavior that measures the time needed by a component to render itself. MarkupContainer's render includes the time for rendering its children so the time accumulates.
To enable this listener use the following in YourApplication.init():
```
 getComponentInstantiationListeners().add(new RenderPerformanceListener());
 
```
