Class Until<A>

java.lang.Object

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

Type Parameters:

A - the IO value type

All Implemented Interfaces:

public final class Until<A>
extends Object
implements Fn2<Fn1<? super A, ? extends Boolean>, IO<A>, IO<A>>

Given a predicate function for a value of some type A and an IO that yields a value of type A, produce an IO that repeatedly executes the original IO until the predicate returns true when applied to the yielded value.
