Method Detail

actionPerformed

public void actionPerformed(ActionEvent e)

Invoked when an action occurs.

initialise

public void initialise()

The initialise method is called at the start of a plugin instance life cycle. This method is called to give the plugin a chance to intitialise itself. All plugin initialisation should be done in this method rather than the plugin constructor, since the initialisation might need to occur at a point after plugin instance creation, and a each plugin must have a zero argument constructor.

dispose

public void dispose()

This method is called at the end of a plugin life cycle, when the plugin needs to be removed from the system. Plugins should remove any listeners that they setup and perform other cleanup, so that the plugin can be garbage collected.
