Constructor Detail

PEEventMulticaster

protected PEEventMulticaster(java.util.EventListener a,
                             java.util.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.

---

remove

public static PEMouseInputListener remove(PEMouseInputListener l,
                                          PEMouseInputListener oldl)

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

---

addInternal

protected static java.util.EventListener addInternal(java.util.EventListener a,
                                                     java.util.EventListener b)

Returns the resulting multicast listener from adding listener-a and listener-b together. 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.

---

removeInternal

protected static java.util.EventListener removeInternal(java.util.EventListener l,
                                                        java.util.EventListener oldl)

Returns the resulting multicast listener 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 it removes the old listener from it. Else, returns listener l.
