Class InjectStateWorker

java.lang.Object
  org.apache.tapestry.enhance.InjectStateWorker

All Implemented Interfaces:

InjectEnhancementWorker

public class InjectStateWorker
extends Object
implements InjectEnhancementWorker

Worker for injecting application state objects as properties of the component. These properties are read/write and must be "live" (changes are propogated back into the ApplicationStateManager). They should also cache in a local variable for efficiency, and clear out that variable at the end of the request.

4.0
