Package com.jnape.palatable.lambda.functions.builtin.fn3

Class GTBy<A,B extends Comparable<B>>

java.lang.Object

com.jnape.palatable.lambda.functions.builtin.fn3.GTBy<A,B>

Type Parameters:

A - the value type

B - the mapped comparison type

All Implemented Interfaces:

Fn1<Fn1<? super A,? extends B>,Fn1<A,Fn1<A,Boolean>>>, Fn2<Fn1<? super A,? extends B>,A,Fn1<A,Boolean>>, Fn3<Fn1<? super A,? extends B>,A,A,Boolean>, Applicative<Fn1<A,Fn1<A,Boolean>>,Fn1<Fn1<? super A,? extends B>,?>>, Cartesian<Fn1<? super A,? extends B>,Fn1<A,Fn1<A,Boolean>>,Fn1<?,?>>, Cocartesian<Fn1<? super A,? extends B>,Fn1<A,Fn1<A,Boolean>>,Fn1<?,?>>, Contravariant<Fn1<? super A,? extends B>,Profunctor<?,Fn1<A,Fn1<A,Boolean>>,Fn1<?,?>>>, Functor<Fn1<A,Fn1<A,Boolean>>,Fn1<Fn1<? super A,? extends B>,?>>, Profunctor<Fn1<? super A,? extends B>,Fn1<A,Fn1<A,Boolean>>,Fn1<?,?>>, Monad<Fn1<A,Fn1<A,Boolean>>,Fn1<Fn1<? super A,? extends B>,?>>, MonadReader<Fn1<? super A,? extends B>,Fn1<A,Fn1<A,Boolean>>,Fn1<Fn1<? super A,? extends B>,?>>, MonadRec<Fn1<A,Fn1<A,Boolean>>,Fn1<Fn1<? super A,? extends B>,?>>, MonadWriter<Fn1<? super A,? extends B>,Fn1<A,Fn1<A,Boolean>>,Fn1<Fn1<? super A,? extends B>,?>>

public final class GTBy<A,B extends Comparable<B>>
extends Object
implements Fn3<Fn1<? super A,? extends B>,A,A,Boolean>

Given a mapping function from some type A to some Comparable type B and two values of type A, return true if the second value is strictly greater than the first value in terms of their mapped B results; otherwise, return false.
