Method Detail

getValueBinding

public javax.faces.el.ValueBinding getValueBinding(String binding)

Description copied from class: javax.faces.component.UIComponentBase

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.

Overrides:

getValueBinding in class javax.faces.component.UIComponentBase

Parameters:

binding - Name of the attribute or property for which to retrieve a ValueBinding

Returns:

the value binding.

setValueBinding

public void setValueBinding(String name,
                            javax.faces.el.ValueBinding binding)

Description copied from class: javax.faces.component.UIComponentBase

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

Overrides:

setValueBinding in class javax.faces.component.UIComponentBase

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

getValueExpression

public javax.el.ValueExpression getValueExpression(String name)

Description copied from class: javax.faces.component.UIComponent

Return the ValueExpression used to calculate the value for the specified attribute or property name, if any.

This method must be overridden and implemented for components that comply with Jakarta Server Faces 1.2 and later.

Overrides:

getValueExpression in class javax.faces.component.UIComponent

Parameters:

name - Name of the attribute or property for which to retrieve a ValueExpression

Returns:

the value expression, or null.

setValueExpression

public void setValueExpression(String name,
                               javax.el.ValueExpression arg1)

Description copied from class: javax.faces.component.UIComponent

Set the ValueExpression used to calculate the value for the specified attribute or property name, if any.

The implementation must call Expression.isLiteralText() on the argument expression. If isLiteralText() returns true, invoke ValueExpression.getValue(javax.el.ELContext) on the argument expression and pass the result as the value parameter in a call to this.UIComponent.getAttributes().put(name, value) where name is the argument name. If an exception is thrown as a result of calling ValueExpression.getValue(javax.el.ELContext), wrap it in a FacesException and re-throw it. If isLiteralText() returns false, simply store the un-evaluated expression argument in the collection of ValueExpressions under the key given by the argument name.

This method must be overridden and implemented for components that comply with Jakarta Server Faces 1.2 and later.

Overrides:

setValueExpression in class javax.faces.component.UIComponent

Parameters:

name - Name of the attribute or property for which to set a ValueExpression

arg1 - The ValueExpression to set, or null to remove any currently set ValueExpression

getFamily

public String getFamily()

Description copied from class: javax.faces.component.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

Specified by:

getFamily in class javax.faces.component.UIComponent

Returns:

the component family (not null).

getParent

public javax.faces.component.UIComponent getParent()

Description copied from class: javax.faces.component.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( ).

Overrides:

getParent in class javax.faces.component.UIComponentBase

Returns:

the parent component.

setParent

public void setParent(javax.faces.component.UIComponent parent)

Description copied from class: 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

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.

Overrides:

setParent in class javax.faces.component.UIComponentBase

Parameters:

parent - The new parent, or null for the root node of a component tree

getRendererType

public String getRendererType()

Description copied from class: javax.faces.component.UIComponent

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

Overrides:

getRendererType in class javax.faces.component.UIComponentBase

Returns:

the renderer type.

setRendererType

public void setRendererType(String rendererType)

Description copied from class: javax.faces.component.UIComponent

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

Overrides:

setRendererType in class javax.faces.component.UIComponentBase

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: 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 Jakarta Server Faces Specification, component authors are encouraged to return true from this method and rely on UIComponentBase.encodeChildren(javax.faces.context.FacesContext).

Overrides:

getRendersChildren in class javax.faces.component.UIComponentBase

Returns:

true if the component renders its children, false otherwise.

getChildren

public List<javax.faces.component.UIComponent> getChildren()

Description copied from class: javax.faces.component.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:

• The List implementation must implement the java.io.Serializable interface.
• Any attempt to add a null must throw a NullPointerException
• Any attempt to add an object that does not implement UIComponent must throw a ClassCastException.
• Whenever a new child component is added, the 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).
• Whenever an existing child component is removed, the 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.class as the first argument and the newly added component as the second argument if any the following cases 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

Overrides:

getChildren in class javax.faces.component.UIComponentBase

Returns:

the list of children.

getChildCount

public int getChildCount()

Description copied from class: javax.faces.component.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.

Overrides:

getChildCount in class javax.faces.component.UIComponentBase

Returns:

the number of child components.

findComponent

public javax.faces.component.UIComponent findComponent(String id)

Description copied from class: 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 Jakarta Expression Language-bound attribute from the component is not safe. Jakarta Expression Language 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:

• Identify the UIComponent that will be the base for searching, by stopping as soon as one of the following conditions is met:
  • If the search expression begins with the the separator character (called an "absolute" search expression), the base will be the root 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.
  • Otherwise, if this UIComponent is a NamingContainer it will serve as the basis.
  • Otherwise, search up the parents of this component. If a NamingContainer is encountered, it will be the base.
  • Otherwise (if no NamingContainer is encountered) the root UIComponent will be the base.
• The search expression (possibly modified in the previous step) is now a "relative" search expression that will be used to locate the component (if any) that has an id that matches, within the scope of the base component. The match is performed as follows:
  • If the search expression is a simple identifier, this value is compared to the 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).
  • If the search expression includes more than one identifier separated by the separator character, the first identifier is used to locate a NamingContainer by the rules in the previous bullet point. Then, the findComponent() method of this NamingContainer will be called, passing the remainder of the search expression.

Overrides:

findComponent in class javax.faces.component.UIComponentBase

Parameters:

id - Search expression identifying the UIComponent to be returned

Returns:

the found UIComponent, or null if the component was not found.

getFacets

public Map<String,javax.faces.component.UIComponent> getFacets()

Description copied from class: javax.faces.component.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:

• The Map implementation must implement the java.io.Serializable interface.
• Any attempt to add a null key or value must throw a NullPointerException.
• Any attempt to add a key that is not a String must throw a ClassCastException.
• Any attempt to add a value that is not a UIComponent must throw a ClassCastException.
• Whenever a new facet UIComponent is added:
  • The parent property of the component must be set to this component instance.
  • If the parent property of the component was already non-null, the component must first be removed from its previous parent (where it may have been either a child or a facet).
• Whenever an existing facet UIComponent is removed:
  • The parent property of the facet must be set to null.

Overrides:

getFacets in class javax.faces.component.UIComponentBase

Returns:

the map of facets.

getFacetCount

public int getFacetCount()

Description copied from class: javax.faces.component.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 UIComponentBase.getFacetCount().

Overrides:

getFacetCount in class javax.faces.component.UIComponentBase

Returns:

the number of facets.

getFacet

public javax.faces.component.UIComponent getFacet(String name)

Description copied from class: javax.faces.component.UIComponent

Parameters:

name - Name of the desired facet

Returns:

the component, or null.

getFacetsAndChildren

public Iterator<javax.faces.component.UIComponent> getFacetsAndChildren()

Description copied from class: javax.faces.component.UIComponent

Return an Iterator over the facet followed by child UIComponents 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.

Overrides:

getFacetsAndChildren in class javax.faces.component.UIComponentBase

Returns:

the facets and children iterator.
