org.apache.cocoon.sunshine.context.SessionContext
Interface for a SessionContext. This interface describes a SessionContext. The SessionContext is a data container containing structured XML which can be retrieved/set by the sunshine transformer. This interface does not specify how the session context stores the data. This is left to the implementation itself, but actually this interface is build in the DOM model. As this context is used in a web context, all methods must be synchronized. @author Carsten Ziegeler @version CVS $Id: SessionContext.java,v 1.2 2002/02/22 06:57:17 cziegeler Exp $
