Interface Trampoline<T>

Type Parameters:

T - Return type

All Superinterfaces:

Convertable<T>, Fn0<T>, Folds<T>, java.lang.Iterable<T>, java.util.function.Predicate<T>, org.reactivestreams.Publisher<T>, java.util.function.Supplier<T>, To<Trampoline<T>>, Value<T>, Visitable<T>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface Trampoline<T>
extends Value<T>, To<Trampoline<T>>

simple Trampoline implementation : inspired by excellent TotallyLazy Java 8 impl and Mario Fusco presentation Allows Stack Free Recursion
