T1 - the component type of the 1st Option

T2 - the component type of the 2nd Option

T3 - the component type of the 3rd Option

T4 - the component type of the 4th Option

T5 - the component type of the 5th Option

T6 - the component type of the 6th Option

Enclosing class:

API

public static class API.ForLazy8Option<T1,T2,T3,T4,T5,T6,T7,T8>
extends java.lang.Object

A lazily evaluated For-comprehension with 8 Options.

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

Method Detail

yield

public <R> Option<R> yield(@NonNull Function8<? super T1,? super T2,? super T3,? super T4,? super T5,? super T6,? super T7,? super T8,? extends R> f)

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

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

Type Parameters:

R - the element type of the resulting Option

Parameters:

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

Returns:

an Option containing mapped results

Throws:

java.lang.NullPointerException - if f is null
