Field Detail

listenerList

private static AppliListener[] listenerList

The list of AppliListeners.

Constructor Detail

AppliEventListenerList

public AppliEventListenerList()

Creates a new AppliEventListenerList.

Method Detail

getListenerList

public AppliListener[] getListenerList()

This passes back the event listener list as an array of AppliListener.
Note that for performance reasons, this implementation passes back the actual data structure in which the listner data is stored internally!
This method is guaranteed to pass back a non-null array, so that no null-checking is required in fire methods.
A zero-length array of Object should be returned if there are currently no listeners.

WARNING!!! Absolutely NO modification of the data contained in this array should be made.
if any such manipulation is necessary, it should be done on a copy of the array returned rather than the array itself.

Returns:

The AppliListener array.

public final int getListenerCount()

Returns the total number of listeners for this listenerlist.

Returns:
