public java.lang.String getFamily()
UIComponentReturn 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.
getFamily in class UIComponentpublic 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 request
public boolean visitTree(VisitContext context,
VisitCallback callback)
UIComponentPerform a tree visit starting at this node in the tree.
UIComponent.visitTree() implementations do not invoke the
VisitCallback directly, but instead call VisitContext#invokeVisitCallback 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.
visitTree in class UIComponentcontext - the VisitContext for this visitcallback - the VisitCallback instance
whose visit method will be called
for each node visited.
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.
UIComponent#visitTree
public java.lang.String createUniqueId(FacesContext context,
java.lang.String seed)
UniqueIdVendorGenerate 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.
createUniqueId in interface UniqueIdVendorcontext - FacesContextseed - an optional seed value - e.g. based on the position of the component in the VDL-template
