RWWithObjectInputContext()

~RWWithObjectInputContext()

#include <rw/serial/RWObjectInputStream.h>

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

// Read in one or more objects from an object stream that 
// were output in the same context.

#include <rw/serial/RWCompactObjectInputStreamImp.h>
#include <rw/serial/RWObjectInputStream.h>
#include <fstream.h>
#include <iostream.h>

int main() {
  ifstream fstrm;
  fstrm.open("RWWithObjectOutputContext.out",
    ios::in | ios::nocreate);

  if (!fstrm) {
    cout << "The file does not exist."<< endl;
  }

  else {
    RWObjectInputStream in = 
      RWCompactObjectInputStreamImp::make(fstrm);

    RWWithObjectInputContext context(in);

    int i,j;
    
    in >> i >> j;
    cout << "i = " << i << "  j = " << j << endl;

  }
  return 0;
}

RWWithObjectInputContext(RWObjectInputStream& strm, bool readContext = true);

Constructor taking object input stream reference argument. If readContext is true then read in any document header at the outer context.

RWWithObjectInputContext(RWObjectInputStreamImp* strm, bool readContext = true);

Constructor taking object input stream pointer argument. If readContext is true then read in any document header at the outer context.

~RWWithObjectInputContext();

Destructor automatically closes context.
