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;
};

cwprint_using

Example:

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

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