Class MakeAdapters 

java.lang.Object
   |
   +----MakeAdapters
public class MakeAdapters
extends Object
Creates event listener/adapter pairs automatically. Written because I abhor inner classes. Once created these can be used as needed. Recommend you "final" any implemented call back routines in case a subclass extends your class and tries to use the same call back.

Usage is: 

 java MakeAdapters event_type event_method num_adapters [destination_package] [base_class]
For example: 
 java MakeAdapters action Performed 1
creates the interface ActionPerformedOnAListener and the adapter class ActionPeformedAdapterA.

Variable Index

o ADAPTERSTRING
"Adapter"
o DESTPACKAGE
Default package for event adapter/listeners.
o EVENTPACKAGE
The Java AWT Event package.
o LISTENEREXTENDS
Java base interface for event listeners.
o LISTENERSTRING
"Listener"
o MOTION
"Motion"
o stupidmousemotion
Is the event a MouseMotion event? Stupid? Well, every other event in the AWT has the name FooEvent, where "Foo" also serves as the prefix to all the event's methods EXCEPT MouseMotion.
o THELISTENER
Name for the listener ("listener").
