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(Object), not ==.
