Interface BridgePublicRenderParameterHandler

public interface BridgePublicRenderParameterHandler

The BridgePublicRenderParameterHandler interface defines the class the bridge relies on to post process portlet public render parameters. The handler provides the portlet a means for resynching application state following any model updates that resulted from the bridge pushing changed public render parameter values based on declarative mappings. After the bridge pushes such values the bridge calls the handler if it has been configured during bridge init(). Though the FacesContext has been acquired before the portlet is called to process these updates, the Lifecycle has not been acquired or run. Because of this is is no current active view. Unlike events, one can't navigate based on a public render parameter change.

Method Detail

processUpdates

void processUpdates(javax.faces.context.FacesContext context)

Called by the bridge after pushing incoming public render parameter values into mapped managed beans. Only called if there is at least one public render parameter in the incoming request whose value is different (updates) the underlying bean. This give the portlet an opportunity to perform further computations based on these changes to resynchronize its application state.

Parameters:

context - current FacesContext. A Lifecycle has been acquired and the current view restored.
