Class LayoutDispatcher

java.lang.Object
  org.jboss.portal.theme.LayoutDispatcher

All Implemented Interfaces:

RequestDispatchCallback

public final class LayoutDispatcher
extends java.lang.Object
implements RequestDispatchCallback

Dispatches the request to the target layout. The major side effect is to change the context path returned by the request to the value returned by PortalLayout#getContextPath() so the layout can safely use the getContextPath in order to designates resources located in the same web application.
