Composition vs Contravariance - What's the difference?

As nouns the difference between composition and contravariance

is that composition is the proportion of different parts to make a whole while contravariance is (label) the reversal of the order of data types acted upon by an operator.

Functor vs Contravariance - What's the difference?

functor | contravariance |


In category theory terms the difference between functor and contravariance

is that functor is a structure-preserving mapping between categories: if F is a functor from category C to category D, then F maps objects of C to objects of D and morphisms of C to morphisms of D such that any morphism f:XY of C is mapped to a morphism F(f): F(X) → F(Y) of D, such that if h = g \circ f then F(h) = F(g) \circ F(f), and such that identity morphisms (and only identity morphisms) are mapped to identity morphisms. Note: the functor just described is covariant while contravariance is a functor which reverses composition.
