public abstract class UIComponentBase
extends UIComponent

UIComponentBase is a convenience base class that implements the default concrete behavior of all methods defined by UIComponent.

By default, this class defines getRendersChildren() to find the renderer for this component and call its getRendersChildren() method. The default implementation on the Renderer 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 the implementation of encodeChildren(javax.faces.context.FacesContext) in this class and in the Renderer (Renderer.encodeChildren(javax.faces.context.FacesContext, javax.faces.component.UIComponent)). Subclasses that wish to manage the rendering of their children should override this method to return true instead.

Method Detail

getAttributes

public Map<String,Object> getAttributes()
Description copied from class: UIComponent

Return a mutable Map representing the attributes (and properties, see below) associated wth this UIComponent, keyed by attribute 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:

Specified by:
getAttributes in class UIComponent

getValueBinding

public ValueBinding getValueBinding(String name)
Deprecated. This has been replaced by UIComponent.getValueExpression(java.lang.String).

Call through to UIComponent.getValueExpression(java.lang.String) and examine the result. If the result is an instance of the wrapper class mandated in UIComponent.setValueBinding(java.lang.String, javax.faces.el.ValueBinding), extract the ValueBinding instance and return it. Otherwise, wrap the result in an implementation of ValueBinding, and return it.

Specified by:
getValueBinding in class UIComponent
Parameters:
name - Name of the attribute or property for which to retrieve a ValueBinding
Throws:
NullPointerException - if name is null

setValueBinding

public void setValueBinding(String name,
                            ValueBinding binding)
Deprecated. This has been replaced by UIComponent.setValueExpression(java.lang.String, javax.el.ValueExpression).

Wrap the argument binding in an implementation of ValueExpression and call through to UIComponent.setValueExpression(java.lang.String, javax.el.ValueExpression).

Specified by:
setValueBinding in class UIComponent
Parameters:
name - Name of the attribute or property for which to set a ValueBinding
binding - The ValueBinding to set, or null to remove any currently set ValueBinding
Throws:
IllegalArgumentException - if name is one of id or parent
NullPointerException - if name is null

getClientId

public String getClientId(FacesContext context)
Description copied from class: UIComponent

Return a client-side identifier for this component, generating one if necessary. The associated Renderer, if any, will be asked to convert the clientId to a form suitable for transmission to the client.

The return from this method must be the same value throughout the lifetime of the instance, unless the id property of the component is changed, or the component is placed in a NamingContainer whose client ID changes (for example, UIData). However, even in these cases, consecutive calls to this method must always return the same value. The implementation must follow these steps in determining the clientId:

Find the closest ancestor to this component in the view hierarchy that implements NamingContainer. Call getContainerClientId() on it and save the result as the parentId local variable. Call UIComponent.getId() on this component and save the result as the myId local variable. If myId is null, call context.getViewRoot().createUniqueId() and assign the result to myId. If parentId is non-null, let myId equal parentId + UINamingContainer.getSeparatorChar(javax.faces.context.FacesContext) + myId. Call Renderer.convertClientId(javax.faces.context.FacesContext, java.lang.String), passing myId, and return the result.

Specified by:
getClientId in class UIComponent
Parameters:
context - The FacesContext for the current request
Throws:
NullPointerException - if context is null

getId

public String getId()
Description copied from class: UIComponent

Return the component identifier of this UIComponent.

Specified by:
getId in class UIComponent

setId

public void setId(String id)
Description copied from class: UIComponent

Set the component identifier of this UIComponent (if any). Component identifiers must obey the following syntax restrictions:

Component identifiers must also obey the following semantic restrictions (note that this restriction is NOT enforced by the setId() implementation):

Specified by:
setId in class UIComponent
Parameters:
id - The new component identifier, or null to indicate that this UIComponent does not have a component identifier
Throws:
IllegalArgumentException - if id is not syntactically valid
IllegalStateException

getParent

public UIComponent getParent()
Description copied from class: UIComponent

Return the parent UIComponent of this UIComponent, if any. A component must allow child components to be added to and removed from the list of children of this component, even though the child component returns null from getParent( ).

Specified by:
getParent in class UIComponent

setParent

public void setParent(UIComponent parent)
Description copied from class: UIComponent

Set the parent UIComponent of this UIComponent. This method will cause an PostAddToViewEvent to be published and if parent.isInView() returns true an PostAddToViewEvent will be published as well. This method must never be called by developers; a UIComponent's internal implementation will call it as components are added to or removed from a parent's child List or facet Map.

Specified by:
setParent in class UIComponent
Parameters:
parent - The new parent, or null for the root node of a component tree

isRendered

public boolean isRendered()
Description copied from class: UIComponent

Return true if this component (and its children) should be rendered during the Render Response phase of the request processing lifecycle.

Specified by:
isRendered in class UIComponent

setRendered

public void setRendered(boolean rendered)
Description copied from class: UIComponent

Set the rendered property of this UIComponent.

Specified by:
setRendered in class UIComponent
Parameters:
rendered - If true render this component; otherwise, do not render this component

getRendererType

public String getRendererType()
Description copied from class: UIComponent

Return the Renderer type for this UIComponent (if any).

Specified by:
getRendererType in class UIComponent

setRendererType

public void setRendererType(String rendererType)
Description copied from class: UIComponent

Set the Renderer type for this UIComponent, or null for components that render themselves.

Specified by:
setRendererType in class UIComponent
Parameters:
rendererType - Logical identifier of the type of Renderer to use, or null for components that render themselves

getRendersChildren

public boolean getRendersChildren()
Description copied from class: UIComponent

Return a flag indicating whether this component is responsible for rendering its child components. The default implementation in 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 encodeChildren(javax.faces.context.FacesContext).

Specified by:
getRendersChildren in class UIComponent

getChildren

public List<UIComponent> getChildren()
Description copied from class: UIComponent

Return a mutable List representing the child UIComponents associated with this component. The returned implementation must support all of the standard and optional List methods, plus support the following additional requirements:

Specified by:
getChildren in class UIComponent

getChildCount

public int getChildCount()
Description copied from class: UIComponent

Return the number of child UIComponents 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.

Specified by:
getChildCount in class UIComponent

findComponent

public UIComponent findComponent(String expr)
Description copied from class: UIComponent

Search for and return the UIComponent with an id that matches the specified search expression (if any), according to the algorithm described below.

For a method to find a component given a simple clientId, see UIComponent.invokeOnComponent(javax.faces.context.FacesContext, java.lang.String, javax.faces.component.ContextCallback).

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:

Specified by:
findComponent in class UIComponent
Parameters:
expr - Search expression identifying the UIComponent to be returned
Returns:
the found UIComponent, or null if the component was not found.
Throws:
NullPointerException - if expr is null

invokeOnComponent

public boolean invokeOnComponent(FacesContext context,
                                 String clientId,
                                 ContextCallback callback)
                          throws FacesException

Starting at this component in the View hierarchy, search for a component with a clientId equal to the argument clientId and, if found, call the ContextCallback.invokeContextCallback(javax.faces.context.FacesContext, javax.faces.component.UIComponent) method on the argument callback, passing the current FacesContext and the found component as arguments. This method is similar to UIComponent.findComponent(java.lang.String) but it does not support the leading UINamingContainer.getSeparatorChar(javax.faces.context.FacesContext) syntax for searching from the root of the View.

The default implementation will first check if this.getClientId() is equal to the argument clientId. If so, call the ContextCallback.invokeContextCallback(javax.faces.context.FacesContext, javax.faces.component.UIComponent) method on the argument callback, passing through the FacesContext argument and passing this as the component argument. If an Exception is thrown by the callback, wrap it in a FacesException and re-throw it. Otherwise, return true.

Otherwise, for each component returned by UIComponent.getFacetsAndChildren(), call invokeOnComponent() passing the arguments to this method, in order. The first time invokeOnComponent() returns true, abort traversing the rest of the Iterator and return true.

When calling ContextCallback.invokeContextCallback(javax.faces.context.FacesContext, javax.faces.component.UIComponent) the implementation of this method must guarantee that the state of the component passed to the callback correctly reflects the component's position in the View hierarchy with respect to any state found in the argument clientId. For example, an iterating component such as UIData will need to set its row index to correctly reflect the argument clientId before finding the appropriate child component backed by the correct row. When the callback returns, either normally or by throwing an Exception the implementation of this method must restore the state of the view to the way it was before invoking the callback.

If none of the elements from UIComponent.getFacetsAndChildren() returned true from invokeOnComponent(), return false.

Simple usage example to find a component by clientId.


private UIComponent found = null;

private void doFind(FacesContext context, String clientId) {
  context.getViewRoot().invokeOnComponent(context, clientId,
      new ContextCallback() {
         public void invokeContextCallback(FacesContext context,
                                       UIComponent component) {
           found = component;
         }
      });
}
 

Overrides:
invokeOnComponent in class UIComponent
Parameters:
context - the FacesContext for the current request
clientId - the client identifier of the component to be passed to the argument callback.
callback - an implementation of the Callback interface.
Returns:
true if the a component with the given clientId is found, the callback method was successfully invoked passing that component as an argument, and no Exception was thrown. Returns false if no component with the given clientId is found.
Throws:
NullPointerException - if any of the arguments are null
FacesException - if the argument Callback throws an Exception, it is wrapped in a FacesException and re-thrown.
Since:
1.2

getFacets

public Map<String,UIComponent> getFacets()
Description copied from class: UIComponent

Return a mutable Map representing the facet UIComponents 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:

Specified by:
getFacets in class UIComponent

getFacetCount

public int getFacetCount()
Description copied from class: UIComponent

Return the number of facet UIComponents 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 getFacetCount().

Overrides:
getFacetCount in class UIComponent

getFacet

public UIComponent getFacet(String name)
Description copied from class: UIComponent

addFacesListener

protected void addFacesListener(FacesListener listener)

Add the specified FacesListener to the set of listeners registered to receive event notifications from this UIComponent. 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 {

public void processRestoreState(FacesContext context,
                                Object state)
Description copied from class: UIComponent

Perform the component tree processing required by the Restore View phase of the request processing lifecycle for all facets of this component, all children of this component, and this component itself, as follows.

This method may not be called if the state saving method is set to server.

Specified by:
processRestoreState in class UIComponent
Parameters:
context - FacesContext for the request we are processing
Throws:
NullPointerException - if context is null

getFacesContext

protected FacesContext getFacesContext()
Description copied from class: UIComponent

Convenience method to return the FacesContext instance for the current request.

Specified by:
getFacesContext in class UIComponent

getRenderer

protected Renderer getRenderer(FacesContext context)
Description copied from class: UIComponent

Convenience method to return the Renderer instance associated with this component, if any; otherwise, return null.

Specified by:
getRenderer in class UIComponent
Parameters:
context - FacesContext for the current request

markInitialState

public void markInitialState()

For each of the attached objects on this instance that implement PartialStateHolder, call PartialStateHolder.markInitialState() on the attached object.

Specified by:
markInitialState in interface PartialStateHolder
Overrides:
markInitialState in class UIComponent
Since:
2.0

clearInitialState

public void clearInitialState()

For each of the attached objects on this instance that implement PartialStateHolder, call PartialStateHolder.clearInitialState() on the attached object.

Specified by:
clearInitialState in interface PartialStateHolder
Overrides:
clearInitialState in class UIComponent
Since:
2.0

saveState

public Object saveState(FacesContext context)
Description copied from interface: StateHolder

Gets the state of the instance as a Serializable Object.

If the class that implements this interface has references to instances that implement StateHolder (such as a UIComponent with event handlers, validators, etc.) this method must call the StateHolder.saveState(javax.faces.context.FacesContext) method on all those instances as well. This method must not save the state of children and facets. That is done via the StateManager

This method must not alter the state of the implementing object. In other words, after executing this code:

 Object state = component.saveState(facesContext);
 

component should be the same as before executing it.

The return from this method must be Serializable


restoreState

public void restoreState(FacesContext context,
                         Object state)
Description copied from interface: StateHolder

Perform any processing required to restore the state from the entries in the state Object.

If the class that implements this interface has references to instances that also implement StateHolder (such as a UIComponent with event handlers, validators, etc.) this method must call the StateHolder.restoreState(javax.faces.context.FacesContext, java.lang.Object) method on all those instances as well.


isTransient

public boolean isTransient()
Description copied from interface: StateHolder

If true, the Object implementing this interface must not participate in state saving or restoring.


setTransient

public void setTransient(boolean transientFlag)
Description copied from interface: StateHolder

Denotes whether or not the Object implementing this interface must or must not participate in state saving or restoring.

Parameters:
transientFlag - boolean pass true if this Object will participate in state saving or restoring, otherwise pass false.

saveAttachedState

public static Object saveAttachedState(FacesContext context,
                                       Object attachedObject)

This method is called by UIComponent subclasses that want to save one or more attached objects. It is a convenience method that does the work of saving attached objects that may or may not implement the StateHolder interface. Using this method implies the use of restoreAttachedState(javax.faces.context.FacesContext, java.lang.Object) to restore the attached objects.

This method supports saving attached objects of the following type: Objects, null values, and Collections of these objects. If any contained objects are not Collections and do not implement StateHolder, they must have zero-argument public constructors. The exact structure of the returned object is undefined and opaque, but will be serializable.

Parameters:
context - the FacesContext for this request.
attachedObject - the object, which may be a List instance, or an Object. The attachedObject (or the elements that comprise attachedObject may implement StateHolder.
Throws:
NullPointerException - if the context argument is null.

restoreAttachedState

public static Object restoreAttachedState(FacesContext context,
                                          Object stateObj)
                                   throws IllegalStateException

This method is called by UIComponent subclasses that need to restore the objects they saved using saveAttachedState(javax.faces.context.FacesContext, java.lang.Object). This method is tightly coupled with saveAttachedState(javax.faces.context.FacesContext, java.lang.Object).

This method supports restoring all attached objects types supported by saveAttachedState(javax.faces.context.FacesContext, java.lang.Object).

Parameters:
context - the FacesContext for this request
stateObj - the opaque object returned from saveAttachedState(javax.faces.context.FacesContext, java.lang.Object)
Throws:
NullPointerException - if context is null.
IllegalStateException - if the object is not previously returned by saveAttachedState(javax.faces.context.FacesContext, java.lang.Object).

addClientBehavior

public void addClientBehavior(String eventName,
                              ClientBehavior behavior)

This is a default implementation of ClientBehaviorHolder.addClientBehavior(java.lang.String, javax.faces.component.behavior.ClientBehavior). UIComponent does not implement the ClientBehaviorHolder interface, but provides default implementations for the methods defined by ClientBehaviorHolder to simplify subclass implementations. Subclasses that wish to support the ClientBehaviorHolder contract must declare that the subclass implements ClientBehaviorHolder, and must provide an implementation of ClientBehaviorHolder.getEventNames().

Parameters:
eventName - the logical name of the client-side event to attach the behavior to.
behavior - the Behavior instance to attach for the specified event name.
Since:
2.0

getEventNames

public Collection<String> getEventNames()

This is a default implementation of ClientBehaviorHolder.getEventNames(). UIComponent does not implement the ClientBehaviorHolder interface, but provides default implementations for the methods defined by ClientBehaviorHolder to simplify subclass implementations. Subclasses that wish to support the ClientBehaviorHolder contract must declare that the subclass implements ClientBehaviorHolder, and must override this method to return a non-Empty Collection of the client event names that the component supports.

Since:
2.0

getClientBehaviors

public Map<String,List<ClientBehavior>> getClientBehaviors()

This is a default implementation of ClientBehaviorHolder.getClientBehaviors(). UIComponent does not implement the ClientBehaviorHolder interface, but provides default implementations for the methods defined by ClientBehaviorHolder to simplify subclass implementations. Subclasses that wish to support the ClientBehaviorHolder contract must declare that the subclass implements ClientBehaviorHolder, and must add an implementation of ClientBehaviorHolder.getEventNames().

Since:
2.0

getDefaultEventName

public String getDefaultEventName()

This is a default implementation of ClientBehaviorHolder.getDefaultEventName(). UIComponent does not implement the ClientBehaviorHolder interface, but provides default implementations for the methods defined by ClientBehaviorHolder to simplify subclass implementations. Subclasses that wish to support the ClientBehaviorHolder contract must declare that the subclass implements ClientBehaviorHolder, and must provide an implementation of ClientBehaviorHolder.getEventNames().
