public class UIParameter extends UIComponentBase
UIParameter is a
UIComponentthat represents an optionally named configuration parameter for a parent component.Parent components should retrieve the value of a parameter by calling
getValue(). In this way, the parameter value can be set directly on the component (viasetValue()), or retrieved indirectly via the value binding expression.In some scenarios, it is necessary to provide a parameter name, in addition to the parameter value that is accessible via the
getValue()method.Renderers that support parameter names on their nestedUIParameterchild components should document their use of this property.

Method Detail
-
getFamily
public java.lang.String getFamily()
Description copied from class:UIComponentReturn the identifier of the component family to which this component belongs. This identifier, in conjunction with the value of the
rendererTypeproperty, may be used to select the appropriateRendererfor this component instance.- Specified by:
getFamilyin classUIComponent
-
getName
public java.lang.String getName()
Return the optional parameter name for this parameter.
-
setName
public void setName(java.lang.String name)
Set the optional parameter name for this parameter.
- Parameters:
name- The new parameter name, ornullfor no name
-
getValue
public java.lang.Object getValue()
Returns the
valueproperty of theUIParameter.
-
setValue
public void setValue(java.lang.Object value)
Sets the
valueproperty of the\UIParameter.- Parameters:
value- the new value
-
isDisable
public boolean isDisable()
Return the value of the
disabledirective for this component. This directive determines whether the parameter value should be disabled by assigning it a null value. If true, thevalueset on this component is ignored.- Since:
- 2.0
-
setDisable
public void setDisable(boolean disable)
Sets the
disableproperty of theUIParameter.- Parameters:
disable-- Since:
- 2.0
