      javax.faces.component.UIComponent
          javax.faces.component.UIComponentBase
              org.richfaces.component.AbstractTreeNode

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.ajax4jsf.component.IterationStateHolder, org.richfaces.component.MetaComponentEncoder, org.richfaces.component.MetaComponentResolver, org.richfaces.event.TreeToggleSource

Direct Known Subclasses:
  UITreeNode

    public abstract class AbstractTreeNode

extends javax.faces.component.UIComponentBase
implements org.richfaces.component.MetaComponentResolver, org.richfaces.component.MetaComponentEncoder, org.ajax4jsf.component.IterationStateHolder, org.richfaces.event.TreeToggleSource

The component is a child component of the component. It represents nodes in the parent tree. The appearance and functionality of each tree node can be customized.
