Class Over<S,T,A,B>

java.lang.Object

com.jnape.palatable.lambda.optics.functions.Over<S,T,A,B>

Type Parameters:

S - the type of the larger value

T - the type of the larger updated value

A - the type of the smaller retrieving value

B - the type of the smaller setting value

public final class Over<S,T,A,B>
extends Object
implements Fn3<Optic<? super Fn1<?,?>, ? super Identity<?>, S, T, A, B>, Fn1<? super A, ? extends B>, S, T>

Given an Optic, a function from A to B, and a "larger" value S, produce a T by retrieving the A from the S, applying the function, and updating the S with the B resulting from the function.

This function is similar to Set, except that it allows the setting value B to be derived from S via function application, rather than provided.
