public static final String COMPONENT_TYPE
The standard component type for this component.
public static final String COMPONENT_FAMILY
The standard component family for this component.
public static final String SEPARATOR_CHAR_PARAM_NAME
The context-param that allows the separator char for clientId strings to be set on a per-web application basis.
public UINamingContainer()
Create a new UINamingContainer
instance with default property
values.
public String getFamily()
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.
Note this method should NOT return null

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.
context
- the FacesContext
for the current requestpublic boolean visitTree(VisitContext context, VisitCallback callback)
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.

public String createUniqueId(FacesContext context, String seed)
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.
