Detailed Description

NonCopyable class.

Sometimes it doesn't make sense for an object to be duplicated. This may be for technical reasons (such as the class representing a limited physical resoruce), and sometimes for practical reasons (such as the class storing lots of information). In C++ this can be enforced by explicitly deleting the copy constructor and assignment operator, or by making them private. The NonCopyable class makes this easy and less error prone to do. To make a class NonCopyable, just inherit (privately) from NonCopyable:

class MyClassCannotBeCopied: private NonCopyable {
  ...
};
