org.jboss.portal.theme
Class LayoutDispatcher

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

All Implemented Interfaces:

FilterCommand

---

public final class LayoutDispatcher

extends java.lang.Object

implements FilterCommand

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.
