Print an object to a debug stream without needing an operator<<. More...

#include <libcwd/cwprint.h>


Detailed Description

Print an object to a debug stream without needing an operator<<.

This utility can be used to print an object to a debug stream without using the normal operator<< of that object (if any exists at all).  The purpose is to allow the printing of objects to debug streams in a different way then when you'd normally print them to say std::cout.

The printable_object (see example below) must have the signature:

 class Class {
   ...
 public:
   void print_on(std::ostream& os) const;
 };
See also:
cwprint_using

Example:

 Dout( dc::channel, cwprint(printable_object) );

this will write printable_object to the debug stream by calling the method print_on.
