public class UIParameter extends UIComponentBase
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. Renderers that support parameter names on their
nested UIParameter child components should document their use of this property.
