Method Detail

notifyListener

void notifyListener(L listener,
                    E event)

Notifies the specified listener of the specified event. Implementors should be aware that this method is not designed to throw any exceptions, as it is called asynchronously by the EventDispatcher thread. This includes cases of RuntimeException which should be caught and dealt with, otherwise the default behaviour is simply to print the stacktrace to System.err.

Parameters:

listener - listener to notify

event - event for which listener is to be notified
