UIParameter is a UIComponent that 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 (via setValue()), 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. javax.faces.render.Renderers that support parameter names on their nested UIParameter child components should document their use of this property.

 public class UIParameter extends UIComponentBase {
     // ------------------------------------------------------ Manifest Constants


The standard component type for this component.

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

Return the optional parameter name for this parameter.

Set the optional parameter name for this parameter.

Return the value of the disable directive for this component. This directive determines whether the parameter value should be disabled by assigning it a null value. If true, the value set on this component is ignored.

    public boolean isDisable() {
        return (BooleangetStateHelper().eval(.false);


Sets the disable property of the UIParameter.
