 * Helper class that provides default implementations of TProtocol methods.

 * prevents TVirtualProtocol methods from causing infinite recursion if the
 * non-virtual methods are not overridden by the TVirtualProtocol subclass.
 *
 * You probably don't want to use this class directly.  Use TVirtualProtocol
 * instead.
