## Class UIHashParameter

- java.lang.Object
- - javax.faces.component.UIComponent
  - - javax.faces.component.UIComponentBase
    - - org.richfaces.component.UIHashParameter

- 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

      public class UIHashParameter
      extends javax.faces.component.UIComponentBase

  The <r:hashParam> component allows client-side parameters to be grouped into a hash map. The hash map can then be passed to the client JavaScript API functions of any RichFaces component.
