Eric,
Well done, although there is one minor change that's required:
private static final byte[] LOCK= new byte[0];
public void initialize(ARPluginContext context) throws ARException {
...
synchronized(LOCK) {
if(myplug == null){
myplug = getInstance();
...
}
}
}
The lock is required because multiple threads can access that method,
and you only want one to create the MyPlugin object.
As a further improvement, I'd use a different object for your singleton,
i.e. separate it from the plugin.
Finally, do remember that in a multi-threaded model, using a singleton
is a bottleneck.
