org.apache.cocoon.components.flow.ContinuationsManager
The interface of the Continuations manager. The continuation manager maintains a forrest of {@link WebContinuation} trees. Each tree defines the flow of control for auser within the application. A WebContinuation is created for a continuation object from the scripting language used. A continuation object in the implementation of the scripting language is an opaque object here. It is only stored inside the WebContinuation, without being interpreted in any way. @author Ovidiu Predescu @since March 19, 2002 @see WebContinuation @version CVS $Id: ContinuationsManager.java,v 1.4 2003/03/20 02:46:32 vgritsenko Exp $
