This item is printed on demand - it takes 3-4 days longer - Neuware -These terms come from category theory, which has a general definition of covariance and contravariance that unifies the computer science definition of these terms with the definition used in vector spaces. This distinction is impor…tant in considering argument and return types of methods in class hierarchies. In object-oriented languages such as C++, if class B is a subtype of class A, then all member functions of B must return the same or narrower set of types as A; the return type is said to be covariant. On the other hand, the member functions of B must take the same or broader set of arguments compared with the member functions of A; the argument type is said to be contravariant. 88 pp. Englisch.
