Class SortBy<A, B extends 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:

Fn1<Fn1<? super A, ? extends B>, Fn1<Iterable<A>, List<A>>>, Fn2<Fn1<? super A, ? extends B>, Iterable<A>, List<A>>, Applicative<Fn1<Iterable<A>, List<A>>, Fn1<Fn1<? super A, ? extends B>, ?>>, Cartesian<Fn1<? super A, ? extends B>, Fn1<Iterable<A>, List<A>>, Fn1<?,?>>, Cocartesian<Fn1<? super A, ? extends B>, Fn1<Iterable<A>, List<A>>, Fn1<?,?>>, Contravariant<Fn1<? super A, ? extends B>, Profunctor<?, Fn1<Iterable<A>, List<A>>, Fn1<?,?>>>, Functor<Fn1<Iterable<A>, List<A>>, Fn1<Fn1<? super A, ? extends B>, ?>>, Profunctor<Fn1<? super A, ? extends B>, Fn1<Iterable<A>, List<A>>, Fn1<?,?>>, Monad<Fn1<Iterable<A>, List<A>>, Fn1<Fn1<? super A, ? extends B>, ?>>, MonadReader<Fn1<? super A, ? extends B>, Fn1<Iterable<A>, List<A>>, Fn1<Fn1<? super A, ? extends B>, ?>>, MonadRec<Fn1<Iterable<A>, List<A>>, Fn1<Fn1<? super A, ? extends B>, ?>>, MonadWriter<Fn1<? super A, ? extends B>, Fn1<Iterable<A>, List<A>>, Fn1<Fn1<? super A, ? extends B>, ?>>

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