 package javax.faces.component;
 
 

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 class UIGraphic extends UIComponentBase {

    
Properties that are tracked by state saving.
 
     enum PropertyKeys {

        

The local value of this UIComponent.

 
         value
     }
 
     // ------------------------------------------------------ Manifest Constants
 

    

The standard component type for this component.

 
     public static final String COMPONENT_TYPE = "javax.faces.Graphic";


    

The standard component family for this component.

 
     public static final String COMPONENT_FAMILY = "javax.faces.Graphic";
 
 
     // ------------------------------------------------------------ Constructors
 

    

Create a new UIGraphic instance with default property values.

 
     public UIGraphic() {
 
         super();
         setRendererType("javax.faces.Image");
 
     }
    // ------------------------------------------------------ Instance Variables
    //private Object value = null;
    // -------------------------------------------------------------- Properties
    public String getFamily() {
        return ();
    }


    

Return the image URL for this UIGraphic. This method is a typesafe alias for getValue().

    public String getUrl() {
        return ((StringgetValue());
    }


    

Set the image URL for this UIGraphic. This method is a typesafe alias for setValue().

Parameters:
url The new image URL
    public void setUrl(String url) {
        setValue(url);
    }




    

Returns the value property of the UIGraphic. This will typically be rendered as an URL.

    public Object getValue() {
        return getStateHelper().eval(.);
    }


    

Sets the value property of the UIGraphic. This will typically be rendered as an URL.

Parameters:
value the new value
    public void setValue(Object value) {
        getStateHelper().put(.value);
    }
    // ---------------------------------------------------------------- Bindings


    

Return any javax.faces.el.ValueBinding set for value if a javax.faces.el.ValueBinding for url is requested; otherwise, perform the default superclass processing for this method.

Deprecated:
This has been replaced by getValueExpression(java.lang.String).
Parameters:
name Name of the attribute or property for which to retrieve a javax.faces.el.ValueBinding
Throws:
java.lang.NullPointerException if name is null
    public ValueBinding getValueBinding(String name) {
        if ("url".equals(name)) {
            return (super.getValueBinding("value"));
        } else {
            return (super.getValueBinding(name));
        }
    }


    

Store any javax.faces.el.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.

Deprecated:
This has been replaced by setValueExpression(java.lang.String,javax.el.ValueExpression).
Parameters:
name Name of the attribute or property for which to set a javax.faces.el.ValueBinding
binding The javax.faces.el.ValueBinding to set, or null to remove any currently set javax.faces.el.ValueBinding
Throws:
java.lang.NullPointerException if name is null
    public void setValueBinding(String nameValueBinding binding) {
        if ("url".equals(name)) {
            super.setValueBinding("value"binding);
        } else {
            super.setValueBinding(namebinding);
        }
    }

    

Return any javax.el.ValueExpression set for value if a javax.el.ValueExpression for url is requested; otherwise, perform the default superclass processing for this method.

Parameters:
name Name of the attribute or property for which to retrieve a javax.el.ValueExpression
Throws:
java.lang.NullPointerException if name is null
Since:
1.2
    public ValueExpression getValueExpression(String name) {
        if ("url".equals(name)) {
            return (super.getValueExpression("value"));
        } else {
            return (super.getValueExpression(name));
        }
    }
    
    

Store any javax.el.ValueExpression specified for url under value instead; otherwise, perform the default superclass processing for this method.

Parameters:
name Name of the attribute or property for which to set a javax.el.ValueExpression
binding The javax.el.ValueExpression to set, or null to remove any currently set javax.el.ValueExpression
Throws:
java.lang.NullPointerException if name is null
Since:
1.2
    public void setValueExpression(String nameValueExpression binding) {
        if ("url".equals(name)) {
            super.setValueExpression("value"binding);
        } else {
            super.setValueExpression(namebinding);
        }
