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

Class $<A,B>

java.lang.Object

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

Type Parameters:

A - the applied Fn1's input type

B - the applied Fn1's output type

All Implemented Interfaces:

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

public final class $<A,B>
extends Object
implements Fn2<Fn1<? super A,? extends B>,A,B>

Function application, represented as a higher-order Fn2 that receives an Fn1 and its argument, and applies it. Useful for treating application as a combinator, e.g.:

 
 List<Fn1<Integer, Integer>> fns     = asList(x -> x + 1, x -> x, x -> x - 1);
 List<Integer>               args    = asList(0, 1, 2);
 Iterable<Integer>           results = zipWith($(), fns, args); // [1, 1, 1]
