Detailed Description

Streaming the DDD transient store from/into a std::istream/std::ostream */.

DDStreamer can be used to write the DDD transient object into a std::ostram and to retrieve them again via an std::istream.

The streamer can also be used together with DDLParser. Once possible usage scenario would be to load most of the geometrical DDD information via the streamer and parse some addional DDD XML documents containing SpecPar-information using DDLParser.

If DDStreamer is used together with DDLParser, the user has to ensure that reading in via DDStreamer::read() is done BEFORE invoking DDLParser to guarantee internal consistensies of the DDD objects.

// writing:
#include<fstream>
std::ofstream file("pers.txt");
DDStreamer streamer(file);
streamer.write();


// reading:
#include<fstream>
std::ifstream file("pers.txt");
DDStreamer streamer(filer);
streamer.read();
