Method Detail

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent e)

Description copied from interface: java.awt.event.ActionListener

This method is invoked when an action occurs.

Specified by:

actionPerformed in interface java.awt.event.ActionListener

---

hasListeners

public final boolean hasListeners()

High speed test to see if any listeners present.

---

dispatch

public final void dispatch(java.awt.event.ActionEvent e)

High speed dispatcher that does not need to be synchronized.

---

find

public int find(java.awt.event.ActionListener listener)

Simple list management that avoids synchronized/functional interface of Vector. Key to this implementation is that all changes are made to a "copy" of the original list. This allows for non-synchronized access of listners when event dispatch is called.

---

add

public final void add(java.awt.event.ActionListener listener)

---

remove

public final void remove(java.awt.event.ActionListener listener)

---

removeAll

public final void removeAll()
