contains

public boolean contains(java.lang.Class t,
                        FilteredEventSupport.ListenerEntry entry)

Checks if, for a given class, there is an equivalent ListenerEntry in the list. Comparison with entry's listener is performed by address, comparison with entry's event filter is made using IEventFilter.sameFilterAs( IEventFilter ).

Parameters:

t - The class to which the entry's listener is associated.

entry - The entry to search equivalence from.

Returns:

true if found.

getListenerEntries

public FilteredEventSupport.ListenerEntry[] getListenerEntries(java.lang.Class t)

getListeners

public java.util.EventListener[] getListeners(java.lang.Class t,
                                              IEventFilter filter)

getListenerCount

public int getListenerCount()

getListenerCount

public int getListenerCount(java.lang.Class t)

add

public void add(java.lang.Class t,
                FilteredEventSupport.ListenerEntry entry)

remove

public void remove(java.lang.Class t,
                   FilteredEventSupport.ListenerEntry entry)

Removes the listener as a listener of the specified type.

Parameters:

t - the type of the listener to be removed

l - the listener to be removed

toString

public java.lang.String toString()

Returns a string representation of the EventListenerList.

Overrides:

toString in class java.lang.Object
