Interface SignalRunnable

All Superinterfaces:

Runnable

All Known Implementing Classes:

ActionProcessor, QManager, ReplayManager, SignalThread, TimeUpdate

public interface SignalRunnable

extends Runnable

This is a variant of the Runnable inteface to be used with the SignalThread class. The reason for defining a new interface is to remind implementors that the run() method must periodically check for signals and handle them.
