/**
 * 

UIOutput is a {@link UIComponent} that has a * value, optionally retrieved from a model tier bean via a value * expression, that is displayed to the user. The user cannot directly * modify the rendered value; it is for display purposes only.

* *

During the Render Response phase of the request processing * lifecycle, the current value of this component must be * converted to a String (if it is not already), according to the following * rules:

*
    *
  • If the current value is not null, and is not already * a String, locate a {@link Converter} (if any) to use * for the conversion, as follows: *
      *
    • If getConverter() returns a non-null {@link Converter}, * use that one, otherwise
    • *
    • If Application.createConverter(Class), passing the * current value's class, returns a non-null {@link Converter}, * use that one.
    • *
  • *
  • If the current value is not null and a {@link Converter} * was located, call its getAsString() method to perform * the conversion.
  • *
  • If the current value is not null but no {@link Converter} * was located, call toString() on the current value to perform * the conversion.
  • *
* *

By default, the rendererType property must be set to * "javax.faces.Text". This value can be changed by calling the * setRendererType() method.
