public class ViewHandlerImpl
extends javax.faces.application.ViewHandler

Custom ViewHandler implementation that adds features specific to the Struts-Faces Integration Library. It leverages the "decorator pattern" customization strategy that JSF supports, by delegating most processing to the ViewHandler instance handed to our constructor.
