Class Iterate<A>

java.lang.Object

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

Type Parameters:

A - The Iterable element type

All Implemented Interfaces:

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

public final class Iterate<A>
extends Object
implements Fn2<Fn1<? super A,? extends A>,A,Iterable<A>>

Lazily generate an infinite Iterable from the successive applications of the function first to the initial seed value, then to the result, and so on; i.e., the result of iterate(x -> x + 1, 0) would produce an infinite Iterable over the elements 0, 1, 2, 3, ... and so on.
