io.vavr.API.ForLazy7Future<T1,T2,T3,T4,T5,T6,T7>

Type Parameters:

T1 - the component type of the 1st Future

T2 - the component type of the 2nd Future

T3 - the component type of the 3rd Future

T4 - the component type of the 4th Future

T5 - the component type of the 5th Future

T6 - the component type of the 6th Future

T7 - the component type of the 7th Future

Enclosing class:

API

public static class API.ForLazy7Future<T1,T2,T3,T4,T5,T6,T7>
extends Object

A lazily evaluated For-comprehension with 7 Futures.

Constructed via For(...) and evaluated by calling yield(...). Construction is side-effect free; underlying Futures are traversed only when yield(...) is invoked.

Method Details

yield

public <R> Future<R> yield(@NonNull Function7<? super T1,? super T2,? super T3,? super T4,? super T5,? super T6,? super T7,? extends R> f)

Produces results by mapping the Cartesian product of all bound values.

Evaluation is lazy and delegated to the underlying Futures by composing flatMap and map chains.

Type Parameters:

R - the element type of the resulting Future

Parameters:

f - a function mapping a tuple of bound values to a result

Returns:

an Future containing mapped results

Throws:

NullPointerException - if f is null
