javax.faces.lifecycle
Interface ViewHandler

public interface ViewHandler

ViewHandler is an interface defining a mechanism by which the Render Response phase of the request processing lifecycle can use a pluggable mechanism to support different response generation technologies. JSF implementations, or JSF-based applications, can register an instance of this interface by calling the setViewHandler() method of the Lifecycle instance used to process incoming requests, prior to receiving the first request.

A default implementation of ViewHandler must be provided by the JSF implementation, which will be utilized unless setViewHandler() is called to establish a different one. This default instance will treat the treeId property of the response component tree as a context-relative path (after prefixing it with a slash), and will perform a RequestDispatcher.forward() call to that path.
