```
public boolean isAppropriateListener(FacesListener listener)

    Return true if the argument FacesListener is an instance of the appropriate listener class that this event supports. The default implementation returns true if the listener is a ComponentSystemEventListener or if super.isAppropriateListener() returns true.
    
    Overrides:
    
    isAppropriateListener in class SystemEvent
    
    Parameters:
    
    listener - FacesListener to evaluate

public void processListener(FacesListener listener)
```
    Broadcast this event instance to the specified FacesListener by calling the superclass's processListener() implementation.
    
    Overrides:
    
    processListener in class SystemEvent
    
    Parameters:
    
    listener - FacesListener to evaluate
