API.ForLazy2Validation

java.lang.Object
- io.vavr.API.ForLazy2Validation<L,T1,T2>

Type Parameters:

L - the common left-hand type of all Validations

T1 - the component type of the 1st Validation

T2 - the component type of the 2nd Validation

Enclosing class:

API
```
public static class API.ForLazy2Validation<L,T1,T2>
extends java.lang.Object
```
A lazily evaluated For-comprehension with two Validations.
Constructed via For(...) and evaluated by calling yield(...). Construction is side-effect free; underlying Validations are traversed only when yield(...) is invoked.

```
public <R> Validation<L,R> yield(@NonNull java.util.function.BiFunction<? super T1,? super T2,? extends R> f)
```
    Produces results by mapping the Cartesian product of all bound values.
    Evaluation is lazy and delegated to the underlying Validations by composing flatMap and map chains.
    
    Type Parameters:
    
    R - the element type of the resulting Validation
    
    Parameters:
    
    f - a function mapping a tuple of bound values to a result
    
    Returns:
    
    an Validation containing mapped results
    
    Throws:
    
    java.lang.NullPointerException - if f is null
