Package com.jnape.palatable.lambda.functions.builtin.fn2

Class SortBy<A,B extends java.lang.Comparable<B>>

java.lang.Object

com.jnape.palatable.lambda.functions.builtin.fn2.SortBy<A,B>

Type Parameters:

A - the input Iterable and output List element type

B - the mapped Comparable type

All Implemented Interfaces:

public final class SortBy<A,B extends java.lang.Comparable<B>>
extends java.lang.Object
implements Fn2<Fn1<? super A,? extends B>,java.lang.Iterable<A>,java.util.List<A>>

Given an Iterable and some mapping function from the Iterable element type to some Comparable type, produce a sorted List of the original elements based on sorting applied to the result of the mapping function. Note that this is both eager and monolithic.
