Macro Definition Documentation

NON_COPYABLE

#define NON_COPYABLE   private: ::Carna::base::noncopyable __noncopyable;

Features class it is placed in as non-copyable.

Example:

class MyClass
{

    NON_COPYABLE

public:

    MyClass();

}; // MyClass

class MyCopyableClass : public MyClass
{

public:

    MyCopyableClass();

    MyCopyableClass( const MyCopyableClass& );

    MyCopyableClass& operator=( const MyCopyableClass& );

}; // MyCopyableClass

This example also shows why the macro variant is to be preferred in place of the noncopyable super-class: In case some derivation becomes copyable, the "is" semantics stay valid.
