org.apache.jetspeed.layout.impl.PortletPlacementContextImpl
Portal Placement Context The purpose of the object is to provide an API that can be used to move a portlet fragment on the page. This includes moving, adding, removing and getting information about portlets that are on the page and portlets that are available to be added to the page. This object represents the fragment contents of a single layout fragment (i.e. nested depth cannot be captured by this object). An important note about this object: This object is really only intended to be used to do a single operation such as "moveabs" or "add". After performing the operation, the hashmap data structures are not correct and should not be used for subsequent operations. The reason they are incorrect is that when a fragment is moved, the coordinate of fragments below it are now different. These could be updated, but it really doesn't serve a purpose since this is a short lived object. @author David Gurney @author David Sean Taylor @author Steve Milek @version $Id: $
