Interface Deferable

All Superinterfaces:

Runnable

All Known Implementing Classes:

DummyApp.Defer

public interface Deferable
extends Runnable

A singleton application that will not start if another instance is active. Any application that wants this behavior must implement these methods. If no inter-application messaging is needed then "send" should return null and "recv" should do nothing.
