libcwd::cwprint_using Interface Reference

Print an object to an ostream using an arbitrary method of that object. More...

#include <libcwd/cwprint.h>

Detailed Description

Print an object to an ostream using an arbitrary method of that object.

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 object (see example below) must have the signature:

class Class {
  ...
public:
  void arbitrary_method_name(std::ostream& os) const;
};

Example:

Dout( dc::channel, cwprint_using(object, &Class::arbitrary_method_name) );

this will write object to the debug stream by calling the method arbitrary_method_name.
