Detailed Description

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.

Example

// 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;
}

Constructor & Destructor Documentation

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

inline

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

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

inline

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

RWWithObjectOutputContext::~RWWithObjectOutputContext ( )

inline

Destructor automatically closes the context.
