Hi,
I am trying to use the serialization library in the following scenario.
1. I create one instance of an object in one process
2. Serialize it either with binary/text archive
3. Then send it through unix local socket to another process where the process deserializes
Whatever examples available, it shows just archiving like below
std::ofstream ofs("filename"); // use it to build and archive boost::archive::text_oarchive oa(ofs); // write class instance being pointed to // to the archive oa << g; /************/
But after this
1. I would like to copy the archived data to a buffer
2. Send the buffer throught a socket something like
boost::asio::write(socket, boost::asio::buffer( buffer, sizeof(buffer));
Can someone help on how I can get this done.
a) use a stringstream so no file is necessary
std::sstream ofs()
b) serialize to binary_oarchive to save time
// use it to build and archive boost::archive::binary_oarchive oa(ofs);
send ofs.get_string()? via your favorite method
One more question: does the call boost::asio::write does serialization internally? If yes, still I would need how to get the buffer as mentioned in the query above a my transmission mechanism might change.
serialization uses any conforming stream you supply to it. streams use streambuf objects. You can use the standard ones or make your own. Robert Ramey
