// Description : This is a generic data block that is passed along to
|
|
// a CallbackObject when a callback is made. It
|
|
// contains data specific to the particular callback
|
|
// type in question.
|
|
//
|
|
// This is actually an abstract base class and contains
|
|
// no data. Specializations of this class will contain
|
|
// the actual data relevant to each callback type.
