## org.richfaces.component
Class UIRegion

    java.lang.Object
      javax.faces.component.UIComponent
          javax.faces.component.UIComponentBase
              org.richfaces.component.AbstractRegion
                  org.richfaces.component.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, org.richfaces.component.AjaxContainer, org.richfaces.component.MetaComponentResolver

    @Generated(value={"RichFaces CDK","4.3.1.Final"})
    public class UIRegion

extends AbstractRegion
implements org.richfaces.component.AjaxContainer, org.richfaces.component.MetaComponentResolver

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.
