tdebindings/dcoppython/shell/marshal_funcs.data

// This file contains the C++ code necessary marshal and demarshal
// all the _simple_ types that dcoppython can understand.
// "Simple" types are types that do not contain other types.
// So, int and TQString are simple types; TQDict, TQMap and TQStringList are not.
// This file is processed by gen_marshal_code.py to produce a header
// file, which is included by marshaller.cpp
//
// Marshalling:
//   The code in the "marshal" section has the following variables available:
//     PyObject * obj; // the object to marshal
//     TQDataStream *str; // the stream to marshal to
//   The function should return true if the object can be marshalled.
//   str may be NULL. If so, the function should ignore the actually marshalling
//   and merely return true or false, depending on whether the object _could_
//   be marshalled.
//
// Demarshalling:
//   The code in the "demarshal" section has the following variables available:
//     TQDataStream *str; // the stream to demarshal from
//   The function should return a PyObject* which is a reference to the
//   newly created object. Ownership of the reference should be passed to
//   the caller. The function can return null if for any reason it
//   could not demarshal.
