dimap

public <A,B,C,D> (Adapter<A::A2,B::B2>) -> Adapter<C::A2,D::B2> dimap((C) -> A g,
                                                                      (B) -> D h)

Description copied from interface: Profunctor

Takes a function from the output type C to the input type A and a function from the input type B to the output type D, and returns a function from a container of A, B to a container of C, D.

A straightforward example of an implementation of dimap is the method Function.andThen(Function). For functions, the expression

 dimap(g, h).apply(f)
 

is equivalent to

 g.andThen(f).andThen(h)
 

Specified by:

dimap in interface Profunctor Adapter<_::A2,_::B2>

Type Parameters:

A - The first input type.

B - The second input type.

C - The first output type.

D - The second output type.

Parameters:

g - A function from output to input.

h - A function from input to output.

Returns:

A function from an input container to an output container.
