javax.faces.context.ExternalContext
sun.com/j2ee/javaserverfaces/1.1_01/docs/api/index.html">JSF Specification @author Manfred Geiler (latest modification by $Author: matzew $) @version $Revision: 358099 $ $Date: 2005-12-20 13:40:00 -0700 (Tue, 20 Dec 2005) $
org.springframework.webflow.context.ExternalContext
A facade that provides normalized access to an external system that has called into the Spring Web Flow system.
This context object provides a normalized interface for internal web flow artifacts to use to reason on and manipulate the state of an external actor calling into SWF to execute flows. It represents the context about a single, external client request to manipulate a flow execution.
The design of this interface was inspired by JSF's own ExternalContext abstraction and shares the same name for consistency. If a particular external client type does not support all methods defined by this interface, they can just be implemented as returning an empty map or null. @author Keith Donald @author Erwin Vervaet @author Jeremy Grelle @author Scott Andrews
