- Field Detail
  - COMPONENT_TYPE
```
public static final String COMPONENT_TYPE
```
    The standard component type for this component.

  - COMPONENT_FAMILY
```
public static final String COMPONENT_FAMILY
```
    The standard component family for this component.

- Method Detail
  - getFamily
```
public String getFamily()
```
    Description copied from class: UIComponent
    
    Return the identifier of the component family to which this component belongs. This identifier, in conjunction with the value of the rendererType property, may be used to select the appropriate Renderer for this component instance.
    
    Specified by:
    
    getFamily in class UIComponent
  - getSeparatorChar
```
public static char getSeparatorChar(FacesContext context)
```
    Return the character used to separate segments of a clientId. The implementation must determine if there is a <context-param> with the value given by the value of the symbolic constant SEPARATOR_CHAR_PARAM_NAME. If there is a value for this param, the first character of the value must be returned from this method. Otherwise, the value of the symbolic constant NamingContainer.SEPARATOR_CHAR must be returned.
    
    Parameters:
    
    context - the FacesContext for the current request
    
    Since:
    
    2.0
  - visitTree
```
public boolean visitTree(VisitContext context,
                         VisitCallback callback)
```
    Description copied from class: UIComponent
    
    Perform a tree visit starting at this node in the tree.
    
    UIComponent.visitTree() implementations do not invoke the VisitCallback directly, but instead call VisitContext.invokeVisitCallback(javax.faces.component.UIComponent, javax.faces.component.visit.VisitCallback) to invoke the callback. This allows VisitContext implementations to provide optimized tree traversals, for example by only calling the VisitCallback for a subset of components.
    
    UIComponent.visitTree() implementations must call UIComponent.pushComponentToEL() before performing the visit and UIComponent.popComponentFromEL() after the visit.
    
    Overrides:
    
    visitTree in class UIComponent
    
    Parameters:
    
    context - the VisitContext for this visit
    
    callback - the VisitCallback instance whose visit method will be called for each node visited.
    
    Returns:
    
    component implementations may return true to indicate that the tree visit is complete (eg. all components that need to be visited have been visited). This results in the tree visit being short-circuited such that no more components are visited.
    
    See Also:
    
    UIComponent.visitTree(javax.faces.component.visit.VisitContext, javax.faces.component.visit.VisitCallback)
  - createUniqueId
```
public String createUniqueId(FacesContext context,
                             String seed)
```
    Description copied from interface: UniqueIdVendor
    
    Generate an identifier for a component. The identifier will be prefixed with UNIQUE_ID_PREFIX, and will be unique within this component-container. Optionally, a unique seed value can be supplied by component creators which should be included in the generated unique id.
    
    Specified by:
    
    createUniqueId in interface UniqueIdVendor
    
    Parameters:
    
    context - FacesContext
    
    seed - an optional seed value - e.g. based on the position of the component in the VDL-template
    
    Returns:
    
    a unique-id in this component-container
