## org.richfaces.component
Class AbstractCommandButton

    java.lang.Object
      javax.faces.component.UIComponent
          javax.faces.component.UIComponentBase
              javax.faces.component.UICommand
                  org.richfaces.component.AbstractActionComponent
                      org.richfaces.component.AbstractCommandButton

All Implemented Interfaces:
  EventListener, javax.faces.component.ActionSource, javax.faces.component.ActionSource2, 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.MetaComponentResolver

Direct Known Subclasses:
  UICommandButton

    public abstract class AbstractCommandButton

extends AbstractActionComponent
implements org.richfaces.component.MetaComponentResolver

The <a4j:commandButton> component is similar to the JavaServer Faces (JSF) <h:commandButton> component, but additionally includes Ajax support.
