RWWithObjectOutputContext()

~RWWithObjectOutputContext()

#include <rw/serial/RWObjectOutputStream.h>

This class consists of a guard object that opens and closes a context within a lexical scope. Simply declare an automatic instance of this class initialized with a object output stream, and all object references within the scope of the automatic variable will be streamed within the same context.

// Output one or more objects in the same context.

#include <rw/serial/RWCompactObjectOutputStreamImp.h>
#include <rw/serial/RWObjectOutputStream.h>
#include <fstream.h>
#include <iostream.h>

int main() {
  ofstream fstrm;
  fstrm.open("RWWithObjectOutputContext.out", ios::out);

  RWObjectOutputStream out = 
    RWCompactObjectOutputStreamImp::make(fstrm);

  RWWithObjectOutputContext context(out);

  int i,j;
  i = 53;
  j = 42;

  out << i << j;

  return 0;
}

RWWithObjectOutputContext(RWObjectOutputStream& strm, bool writeContext = true);

Constructor taking object output stream reference argument. If writeContext is true then write out any document header at the outer context.

RWWithObjectOutputContext(RWObjectOutputStreamImp* strm,  bool writeContext = true);

Constructor taking object output stream pointer argument. If writeContext is true then write out in any document header at the outer context.

~RWWithObjectOutputContext();

Destructor automatically closes context.
