00022 //       Class : CallbackData
00023 // Description : This is a generic data block that is passed along to
00024 //               a CallbackObject when a callback is made.  It
00025 //               contains data specific to the particular callback
00026 //               type in question.
00027 //
00028 //               This is actually an abstract base class and contains
00029 //               no data.  Specializations of this class will contain
00030 //               the actual data relevant to each callback type.
