PSetter

trait PSetter[S, T, A, B] extends Serializable

A PSetter is a generalisation of Functor map:

A PSetter is a generalisation of Functor map:

  • map: (A => B) => F[A] => F[B]
  • modify: (A => B) => S => T

PSetter stands for Polymorphic Setter as it replace and modify methods change a type A to B and S to T. Setter is a type alias for PSetter restricted to monomorphic updates:

type Setter[S, A] = PSetter[S, S, A, A]

PTraversal, POptional, PPrism, PLens and PIso are valid PSetter

Type Params
A

the target of a PSetter

B

the modified target of a PSetter

S

the source of a PSetter

T

the modified source of a PSetter
