```
public SystemEvent(java.lang.Object source)

    Pass the argument source to the superclass constructor.
    
    Parameters:
    
    source - the source reference to be passed to the superclass constructor.
- Method Detail
  - isAppropriateListener
```
public boolean isAppropriateListener(FacesListener listener)
```
    Return true if this FacesListener is an instance of a the appropriate listener class that this event supports. The default implementation returns true if the listener is a ComponentSystemEventListener.
    
    Parameters:
    
    listener - FacesListener to evaluate
  - processListener
```
public void processListener(FacesListener listener)
```
    Broadcast this event instance to the specified FacesListener, by whatever mechanism is appropriate. Typically, this will be accomplished by calling an event processing method, and passing this instance as a paramter.
    
    Parameters:
    
    listener - FacesListener to send this FacesEvent to
    
    Throws:
    
    AbortProcessingException - Signal the JavaServer Faces implementation that no further processing on the current event should be performed
