All Implemented Interfaces:

java.util.EventListener, PartialStateHolder, StateHolder, TransientStateHolder, ComponentSystemEventListener, FacesListener, SystemEventListenerHolder

Direct Known Subclasses:

HtmlGraphicImage
```
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 "javax.faces.Image". This value can be changed by calling the setRendererType() method.

- Method Detail
  - getFamily
```
public java.lang.String getFamily()
```
    Description copied from class: 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 UIComponent
    
    Returns:
    
    the component family (not null).
  - getUrl
```
public java.lang.String getUrl()
```
    Return the image URL for this UIGraphic. This method is a typesafe alias for getValue().
    
    Returns:
    
    the url.
  - setUrl
```
public void setUrl(java.lang.String url)
```
    Set the image URL for this UIGraphic. This method is a typesafe alias for setValue().
    
    Parameters:
    
    url - The new image URL
  - getValue
```
public java.lang.Object getValue()
```
    Returns the value property of the UIGraphic. This will typically be rendered as an URL.
    
    Returns:
    
    the value.
  - setValue
```
public void setValue(java.lang.Object value)
```
    Sets the value property of the UIGraphic. This will typically be rendered as an URL.
    
    Parameters:
    
    value - the new value
  - getValueBinding
```
public ValueBinding getValueBinding(java.lang.String name)
```
    Deprecated. This has been replaced by getValueExpression(java.lang.String).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.
    
    Overrides:
    
    getValueBinding in class UIComponentBase
    
    Parameters:
    
    name - Name of the attribute or property for which to retrieve a ValueBinding
    
    Returns:
    
    the value binding, or null.
    
    Throws:
    
    java.lang.NullPointerException - if name is null
  - setValueBinding
```
public void setValueBinding(java.lang.String name,
                            ValueBinding binding)
```
    Deprecated. This has been replaced by 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.
    
    Overrides:
    
    setValueBinding in class 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
    
    Throws:
    
    java.lang.NullPointerException - if name is null
  - getValueExpression
```
public 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.
    
    Overrides:
    
    getValueExpression in class UIComponent
    
    Parameters:
    
    name - Name of the attribute or property for which to retrieve a ValueExpression
    
    Returns:
    
    the value expression, or null.
    
    Throws:
    
    java.lang.NullPointerException - if name is null
    
    Since:

  - setValueExpression
```
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.
    
    Overrides:
    
    setValueExpression in class UIComponent
    
    Parameters:
    
    name - Name of the attribute or property for which to set a ValueExpression
    
    binding - The ValueExpression to set, or null to remove any currently set ValueExpression
    
    Throws:
    
    java.lang.NullPointerException - if name is null
