Object Reading and Writing
Are there possibilities to automagically map C++ objects to dataharvester tuples?
up until now:
- manually written method for mapping object X to harvest::Tuple
Example:
VertexWriter::save ( const Vertex & vtx ) { Tuple d("vertex"); d["x"]=vtx.x(); d["y"]=vtx.y(); d["z"]=vtx.z(); for trk in tracks { d["trk:weight"]=trk.weight(); d["trk:id"]=trk.id(); d.fill("trk"); } dataharvester::Writer::file(myFileName) << d; }
- future development: : gccxml (or maybe root's genreflex?) conversion for mapping between any object and Tuple.
A GenericObjectWritter would check if an xml description of a class exists. If it does not exist, it should be generated on-the-fly via 'gccxml'. The GenericObjectWriter takes e.g. (void *) pointers to the objects, reads the xml description of the object, and creates a Tuple that includes all data members.
