Examples of org.apache.myfaces.trinidad.context.PartialPageContext

org.apache.myfaces.trinidad.context.PartialPageContext
Context object which is used to track the targets of a partial page render during the Render Response phase. Clients never need to explicitly create PartialPageContext objects, but can retrieve them from a RenderingContext instance. For general access to Partial Page Rendering during all phases, see APIs on the RequestContext API.
During the partial rendering pass, some Renderer implementations may modify the set of partial targets that are rendered. (For example, the FormRenderer adds a partial target for its shared hidden fields.) @version $Name: $ ($Revision: adfrt/faces/adf-faces-impl/src/main/java/oracle/adfinternal/view/faces/renderkit/core/ppr/PartialPageContext.java#0 $) $Date: 10-nov-2005.19:02:58 $ @author The Oracle ADF Faces Team
