public void setParent(javax.faces.component.UIComponent parent)
javax.faces.component.UIComponent
Set the parent
UIComponent
of this UIComponent
. If
parent.isInView()
returns true
, calling
this method will first cause a PreRemoveFromViewEvent
to be published, for
this node, and then the children of this node. Then, once the
re-parenting has occurred, a PostAddToViewEvent
will be published as well,
first for this node, and then for the node's children, but only if any of the
following conditions are true.
FacesContext.getCurrentPhaseId()
returns
PhaseId.RESTORE_VIEW
and partial
state saving is enabled.
FacesContext.isPostback()
returns false
and FacesContext.getCurrentPhaseId()
returns
something other than PhaseId.RESTORE_VIEW

javax.faces.component.UIComponent
Return a flag indicating whether this component is responsible
for rendering its child components. The default implementation
in UIComponentBase.getRendersChildren()
tries to find the
renderer for this component. If it does, it calls Renderer.getRendersChildren()
and returns the result. If it
doesn't, it returns false. As of version 1.2 of the JavaServer
Faces Specification, component authors are encouraged to return
true
from this method and rely on UIComponentBase.encodeChildren(javax.faces.context.FacesContext)
.
getRendersChildren

if the component renders its children, false
otherwise.public List<javax.faces.component.UIComponent> getChildren()
javax.faces.component.UIComponent
Return a mutable
List
representing the child UIComponent
s
associated with this component. The returned implementation must
support all of the standard and optional List
methods, plus support the following additional requirements:
List
implementation must implement the
java.io.Serializable
interface.null
must throw a NullPointerExceptionUIComponent
must throw a ClassCastException.parent
property of
the child must be set to this component instance. If the
parent
property of the child was already non-null,
the child must first be removed from its previous parent (where
it may have been either a child or a facet).parent
property of the child must be set to null
.After the child component has
been added to the view, Application.publishEvent(javax.faces.context.FacesContext, java.lang.Class<? extends javax.faces.event.SystemEvent>, java.lang.Object)
must be
called, passing PostAddToViewEvent

public int getChildCount()
javax.faces.component.UIComponent
Return the number of child UIComponent
s that are
associated with this UIComponent
. If there are no
children, this method must return 0. The method must not cause
the creation of a child component list.
getChildCount
in class javax.faces.component.UIComponentBase
public javax.faces.component.UIComponent findComponent(String id)
javax.faces.component.UIComponent
Search for and
return the UIComponent
with an id
that
matches the specified search expression (if any), according to
the algorithm described below.
WARNING: The found
UIComponent
instance, if any, is returned
without regard for its tree traversal context.
Retrieving an EL-bound attribute from the component is not safe.
EL expressions can contain implicit objects, such as
#{component}
, which assume they are being evaluated
within the scope of a tree traversal context. Evaluating
expressions with these kinds of implicit objects outside of a
tree traversal context produces undefined results. See UIComponent.invokeOnComponent(javax.faces.context.FacesContext, java.lang.String, javax.faces.component.ContextCallback)
for a method that does
correctly account for the tree traversal context when operating
on the found UIComponent
instance. UIComponent.invokeOnComponent(javax.faces.context.FacesContext, java.lang.String, javax.faces.component.ContextCallback)
is also useful to find components given a simple clientId
.
Component identifiers are required to be unique within the scope of
the closest ancestor NamingContainer
that encloses this
component (which might be this component itself). If there are no
NamingContainer
components in the ancestry of this component,
the root component in the tree is treated as if it were a
NamingContainer
, whether or not its class actually implements
the NamingContainer
interface.
A search expression consists of either an identifier
(which is matched exactly against the id
property of
a UIComponent
, or a series of such identifiers linked by
the UINamingContainer.getSeparatorChar(javax.faces.context.FacesContext)
character value.
The search algorithm should operates as follows, though alternate
alogrithms may be used as long as the end result is the same:
UIComponent
that will be the base for searching,
by stopping as soon as one of the following conditions is met:
UIComponent
of the component
tree. The leading separator character will be stripped off,
and the remainder of the search expression will be treated as
a "relative" search expression as described below.UIComponent

the root UIComponent
will be the base.id
that matches, within
the scope of the base component. The match is performed as follows:
id
property, and then recursively
through the facets and children of the base UIComponent
(except that if a descendant NamingContainer
is found,
its own facets and children are not searched).NamingContainer

previous bullet point. Then, the findComponent()
method of this NamingContainer
will be called, passing
the remainder of the search expression.findComponent

javax.faces.component.UIComponent
Return a mutable Map
representing the facet
UIComponent
s associated with this UIComponent
,
keyed by facet name (which must be a String). The returned
implementation must support all of the standard and optional
Map
methods, plus support the following additional
requirements:

the java.io.Serializable
interface.null
key or value must
throw a NullPointerException.UIComponent
must throw a ClassCastException.UIComponent
is added:
parent
property of the component must be set to
this component instance.parent

non-null, the component must first be removed from its previous
parent (where it may have been either a child or a facet).UIComponent
is removed:
parent
property of the facet must be
set to null
.getFacets
in class javax.faces.component.UIComponentBase
public int getFacetCount()
javax.faces.component.UIComponent
Return the number of facet UIComponent
s that are
associated with this UIComponent
. If there are no
facets, this method must return 0. The method must not cause
the creation of a facet component map.
For backwards compatability with classes that extend UIComponent
directly, a default implementation is provided that simply calls
UIComponent.getFacets()
and then calls the size()
method on the
returned Map
. A more optimized version of this method is
provided in UIComponentBase.getFacetCount()
.
getFacetCount
in class javax.faces.component.UIComponentBase
public javax.faces.component.UIComponent getFacet(String name)
javax.faces.component.UIComponent

.public Iterator<javax.faces.component.UIComponent> getFacetsAndChildren()
javax.faces.component.UIComponent
Return an Iterator
over the facet followed by child
UIComponent
s of this UIComponent
.
Facets are returned in an undefined order, followed by
all the children in the order they are stored in the child list. If this
component has no facets or children, an empty Iterator
is returned.
The returned Iterator
must not support the
remove()
operation.

public void broadcast(javax.faces.event.FacesEvent event) throws javax.faces.event.AbortProcessingException
javax.faces.component.UIComponent
Broadcast the specified FacesEvent
to all registered
event listeners who have expressed an interest in events of this
type. Listeners are called in the order in which they were
added.

It is expected that UIComponent
classes acting as event sources
will have corresponding typesafe APIs for registering listeners of the
required type, and the implementation of those registration methods
will delegate to this method. For example:
public class FooEvent extends FacesEvent { ... protected boolean isAppropriateListener(FacesListener listener) { return (listener instanceof FooListener); } protected void processListener(FacesListener listener) { ((FooListener) listener).processFoo(this); } ... } public interface FooListener extends FacesListener { public void processFoo(FooEvent event); } public class FooComponent extends UIComponentBase { ... public void addFooListener(FooListener listener) { addFacesListener(listener); } public void removeFooListener(FooListener listener) { removeFacesListener(listener); } ... }
