javax.faces.component.UIGraphic
public class UIGraphic
UIGraphic is a UIComponent that displays
a graphical image to the user. The user cannot manipulate this component;
it is for display purposes only.
By default, the rendererType property must be set to
"javax.faces.Image". This value can be changed by calling the
setRendererType() method.

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 java.lang.String getUrl()
Return the image URL for this UIGraphic. This method is a
typesafe alias for getValue().
public void setUrl(java.lang.String url)
Set the image URL for this UIGraphic. This method is a
typesafe alias for setValue().
url - The new image URLpublic java.lang.Object getValue()
Returns the value property of the
UIGraphic. This will typically be rendered as an URL.
public void setValue(java.lang.Object value)
Sets the value property of the UIGraphic.
This will typically be rendered as an URL.
value - the new valuepublic ValueBinding getValueBinding(java.lang.String name)
getValueExpression(java.lang.String).
Return any ValueBinding set for value if a
ValueBinding for url is requested; otherwise,
perform the default superclass processing for this method.
getValueBinding in class UIComponentBasename - Name of the attribute or property for which to retrieve
a ValueBinding
java.lang.NullPointerException - if name
is null
public void setValueBinding(java.lang.String name,
ValueBinding binding)
setValueExpression(java.lang.String, javax.el.ValueExpression).
Store any ValueBinding specified for url
under value instead; otherwise, perform the default
superclass processing for this method. In all cases, the
superclass is relied on to convert the ValueBinding
to a ValueExpression.
setValueBinding in class UIComponentBasename - Name of the attribute or property for which to set
a ValueBindingbinding - The ValueBinding to set, or null
to remove any currently set ValueBinding
java.lang.NullPointerException - if name

Return any ValueExpression set for value if a
ValueExpression for url is requested; otherwise,
perform the default superclass processing for this method.
getValueExpression in class UIComponentname - Name of the attribute or property for which to retrieve
a ValueExpression
java.lang.NullPointerException - if name
is null
public void setValueExpression(java.lang.String name,
ValueExpression binding)
Store any ValueExpression specified for url under
value instead; otherwise, perform the default superclass
processing for this method.
setValueExpression in class UIComponentname - Name of the attribute or property for which to set
a ValueExpressionbinding - The ValueExpression to set, or null
