 * PropertyValues implementation created from parameters in a PortletRequest.
 * Can look for all property values beginning with a certain prefix and

 *
 * <p>For example, with a prefix of "spring", "spring_param1" and
 * "spring_param2" result in a Map with "param1" and "param2" as keys.

 * <p>This class is not immutable to be able to efficiently remove property
 * values that should be ignored for binding.
