public class RequestParameterDecoder
extends Object

This class decodes the request parameters in order to set them to a simple specified POJO which attributes are annotated by FormParam or XmlElement annotation.
It is possible to annotate the attribute with UnescapeHtml annotation in order to perform an HTML unescape operation (string type only).
