NON_COPYABLE

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

Marks the class that 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 LibCarna::base::noncopyable base class: In case some derivation becomes copyable, the "is" semantics stay valid.
