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

Class Eq<A>

java.lang.Object

com.jnape.palatable.lambda.functions.builtin.fn2.Eq<A>

Type Parameters:

A - the type to compare for equality

All Implemented Interfaces:

Fn1<A,Fn1<A,Boolean>>, Fn2<A,A,Boolean>, BiPredicate<A,A>, Applicative<Fn1<A,Boolean>,Fn1<A,?>>, Cartesian<A,Fn1<A,Boolean>,Fn1<?,?>>, Cocartesian<A,Fn1<A,Boolean>,Fn1<?,?>>, Contravariant<A,Profunctor<?,Fn1<A,Boolean>,Fn1<?,?>>>, Functor<Fn1<A,Boolean>,Fn1<A,?>>, Profunctor<A,Fn1<A,Boolean>,Fn1<?,?>>, Monad<Fn1<A,Boolean>,Fn1<A,?>>, MonadReader<A,Fn1<A,Boolean>,Fn1<A,?>>, MonadRec<Fn1<A,Boolean>,Fn1<A,?>>, MonadWriter<A,Fn1<A,Boolean>,Fn1<A,?>>

public final class Eq<A>
extends Object
implements BiPredicate<A,A>

Type-safe equality in function form; uses Object.equals(java.lang.Object), not ==.
