Class Inits<A>

java.lang.Object

com.jnape.palatable.lambda.functions.builtin.fn1.Inits<A>

Type Parameters:

A - the Iterable element type

All Implemented Interfaces:

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

public final class Inits<A>
extends Object
implements Fn1<Iterable<A>, Iterable<Iterable<A>>>

Given an Iterable<A>, produce an Iterable<Iterable<A>>, representing all of the subsequences of initial elements, ordered by size, starting with the empty Iterable.

For example, inits(asList(1,2,3)) would iterate [], [1], [1,2], and [1,2,3].
