public class UIGraphic extends UIComponentBase
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 "jakarta.faces.Image". This value can
be changed by calling the setRendererType() method.

Create a new UIGraphic instance with default property values.
public java.lang.String getFamily()
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
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 ValueExpression getValueExpression(java.lang.String name)
Return any ValueExpression set for value if a ValueExpression for url is
requested; otherwise, perform the default superclass processing for this method.
