public class RequestArguments
extends RequestStatics

All arguments related classes are defined in this guy. Argument is the base class for all arguments, which then branches to different still abstract subclasses that specify how are any given HTML input elements being drawn. From these a proper Arguments that define particular value types are then subclassed. When an argument is created, its pointer is stored in the _arguments array list so that the request knows how many arguments and in which order it has. Because request objects and therefore also argument objects one per application, while the codepath can be multithreaded (server decides this), the argument state is not preserved in the argument itself, but in the Record static object that is kept thread local and must be properly initialized at each iteration by calling reset() method on the argument. See the respective classes for more details. NOTE add more arguments to this class as they are needed and keep them here.
