## Class UIRegion

- java.lang.Object
- - javax.faces.component.UIComponent
  - - javax.faces.component.UIComponentBase
    - - org.richfaces.ui.ajax.region.AbstractRegion
      - - org.richfaces.ui.ajax.region.UIRegion

- 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

      @Generated(value={"RichFaces CDK","4.5.0-SNAPSHOT"})
      public class UIRegion
      extends AbstractRegion
      implements AjaxContainer, MetaComponentResolver

  The <r:region> component specifies a part of the JSF component tree to be processed on the server. The region causes all the richfaces 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.
