Introduction

fw::core::UncopyableMixin is an adoption of Item 6: Explicitly disallow the use of compiler-generated functions you do not want from the book Effective C++: 55 Specific Ways to Improve Your Programs and Designs by Scott Meyers.

The implementation uses the following idioms:

• Non-copyable Mixin
• Curiously Recurring Template Pattern (CRTP)

Features

fw::core::UncopyableMixin is a modern version of boost::noncopyable:

• Allows for Empty Base Optimization with multiple inheritance.

• Clean code, e. g. no usage of preprocessor macros.

• Natural name which cleanly indicates its purpose:

  "It's a fine class, I just find the name a bit un-, er, nonnatural."

  -- S. Meyer: Effective C++. Boston: Pearson Education, 2008, p. 39
