Class SimpleUseKey

java.lang.Object
org.kigalisim.engine.state.SimpleUseKey
All Implemented Interfaces:
UseKey
public class SimpleUseKey extends Object implements UseKey
Simple implementation of UseKey that generates keys based on application and substance.

This class provides a lightweight way to generate keys for substance streams without requiring a full Scope object. The key generation follows the same pattern as Scope, using lazy initialization and caching for performance.
