Legacy Support for iostream Output Operators

Although iostream operators have been deprecated from CHM library objects, to ease maintenance of existing applications, we are still providing header files with these operators. The output streaming operators are now defined in CHMostreamOperator.h and CHMostreamOperatorStd.h. To use these operators in your applications, include CHMostreamOperator.h if you are using the old style C++ iostream library or CHMostreamOperatorStd.h if you are using the new standard C++ iostream library. 


#include "HL7appEngine.h"

// using the old style iostream library
#include <iostream.h>

// CHMostreamOperator.h is needed for output 
// stream operators for CHM objects 
#include <CHMostreamOperator.h>

int main()
{
   HL7appEngine Engine;

   Engine.load("interface.vmd");

   // operator<<(ostream& Stream, const CHMengine& Engine)
   // is defined in CHMostreamOperator.h
   cout << Engine;

   ...
   
   return 0;   
}

Using CHMostreamOperator.h


#include "HL7appEngine.h"

// using the new standard iostream library
#include <iostream>
using namespace std;

// CHMostreamOperatorStd.h is needed for output 
// stream operators for CHM objects 
#include <CHMostreamOperatorStd.h>

int main()
{
   HL7appEngine Engine;

   Engine.load("interface.vmd");

   // operator<<(ostream& Stream, const CHMengine& Engine)
   // is defined in CHMostreamOperatorStd.h
   cout << Engine;

   ...
   
   return 0;   
}

Using CHMostreamOperatorStd.h
