Constructor Detail

PEEventMulticaster

protected PEEventMulticaster(EventListener a,
                             EventListener b)

Creates a PEEventMulticaster instance which chains listener-a with listener-b

Method Detail

add

public static PEMouseInputListener add(PEMouseInputListener a,
                                       PEMouseInputListener b)

Adds PEMouseInputListener “a” with PEMouseInputListener “b” and returns the resulting multicast listener.

Parameters:

a - PEMouseInputListener “a”

b - PEMouseInputListener “b”

remove

public static PEMouseInputListener remove(PEMouseInputListener l,
                                          PEMouseInputListener oldl)

Removes the old PEMouseInputListener from PEMouseInputListener-l and returns the resulting multicast listener.

Parameters:

l - PEMouseInputListener-l

oldl - the PEMouseInputListener being removed

remove

protected EventListener remove(EventListener oldl)

Removes a listener from this multicaster and returns the resulting multicast listener.

Overrides:

remove in class AWTEventMulticaster

Parameters:

oldl - the listener to be removed

addInternal

protected static EventListener addInternal(EventListener a,
                                           EventListener b)

Returns the multicast listener resulting from the addition of listener-a and listener-b.
If listener-a is null, it returns listener-b; If listener-b is null, it returns listener-a If neither are null, then it creates and returns a new PEEventMulticaster instance which chains a with b.

Parameters:

a - event listener-a

b - event listener-b

removeInternal

protected static EventListener removeInternal(EventListener l,
                                              EventListener oldl)

Returns the multicast listener obtained after removing the old listener from listener-l.
If listener-l equals the old listener OR listener-l is null, returns null.
Else if listener-l is an instance of AWTEventMulticaster, then removes the old listener from it.
Else, returns listener l.

Parameters:

l - the listener being removed from

oldl - the listener being removed
