Examples of org.apache.jetspeed.layout.PortletPlacementContext

org.apache.jetspeed.layout.PortletPlacementContext
Handles portlet placement for client such as AJAX client side on a per request basis. The context is associated with a request context, thus it is only valid for the span of a request. @author David Gurney @author David Sean Taylor @version $Id: $
