Detailed Description

Utility class that makes any derived class non-copyable.

This class makes its instances non-copyable, by explicitely disabling its copy constructor and its assignment operator.

To create a non-copyable class, simply inherit from cpp3ds::NonCopyable.

The type of inheritance (public or private) doesn't matter, the copy constructor and assignment operator are declared private in cpp3ds::NonCopyable so they will end up being inaccessible in both cases. Thus you can use a shorter syntax for inheriting from it (see below).

Usage example:

class MyNonCopyableClass : cpp3ds::NonCopyable
{
    ...
};

Deciding whether the instances of a class can be copied or not is a very important design choice. You are strongly encouraged to think about it before writing a class, and to use cpp3ds::NonCopyable when necessary to prevent many potential future errors when using it. This is also a very important indication to users of your class.

Default constructor.

Because this class has a copy constructor, the compiler will not automatically generate the default constructor. That's why we must define it explicitely.
