Class AbstractRegion

java.lang.Object

javax.faces.component.UIComponent

javax.faces.component.UIComponentBase

org.richfaces.component.AbstractRegion

All Implemented Interfaces:

EventListener, javax.faces.component.PartialStateHolder, javax.faces.component.StateHolder, javax.faces.component.TransientStateHolder, javax.faces.event.ComponentSystemEventListener, javax.faces.event.FacesListener, javax.faces.event.SystemEventListenerHolder, AjaxContainer, MetaComponentResolver

Direct Known Subclasses:

UIRegion

public abstract class AbstractRegion
extends javax.faces.component.UIComponentBase
implements MetaComponentResolver, AjaxContainer

The <a4j:region> component specifies a part of the JSF component tree to be processed on the server. The region causes all the a4j and rich Ajax controls to execute: decoding, validating, and updating the model. The region causes these components to execute even if not explicitly declared. As such, processing areas can more easily be marked using a declarative approach.

Regions can be nested, in which case only the parent region of the component initiating the request will be processed.

resolveClientId

public String resolveClientId(javax.faces.context.FacesContext facesContext,
                              javax.faces.component.UIComponent contextComponent,
                              String metaId)

Description copied from interface: MetaComponentResolver

Resolves and returns string identifying supported meta-component or null if provided meta-component name is not a supported one.

Specified by:

resolveClientId in interface MetaComponentResolver

Parameters:

facesContext - - current instance of FacesContext

contextComponent - - instance of UIComponent that requested resolution of meta-component

metaId - - name of meta-component (without leading '@' sign)

Returns:

clientId, one of supported meta-names such as @all, @this, etc. or null

substituteUnresolvedClientId

public String substituteUnresolvedClientId(javax.faces.context.FacesContext facesContext,
                                           javax.faces.component.UIComponent contextComponent,
                                           String metaComponentId)

Description copied from interface: MetaComponentResolver

Provides replacement for unresolved meta-component names. Returns identifier string for the chosen substitution or null

Specified by:

substituteUnresolvedClientId in interface MetaComponentResolver

Parameters:

facesContext - - current instance of FacesContext

contextComponent - - instance of UIComponent that requested resolution of meta-component

metaComponentId - - name of meta-component (without leading '@' sign)

Returns:

clientId, one of supported meta-names such as @all, @this, etc. or null
