FailableBiPredicate (Apache Commons Lang 3.12.0 API)

Type Parameters:

T - Predicate type 1.

U - Predicate type 2.

E - Thrown exception.

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 FailableBiPredicate<T,U,E extends Throwable>
```
A functional interface like BiPredicate that declares a Throwable.

Since:

3.11

    Parameters:
    
    other - a predicate that will be logically-ORed with this predicate.
    
    Returns:
    
    a composed FailableBiPredicate like BiPredicate.and(BiPredicate).
    
    Throws:

    Returns:
    
    the predicate's evaluation
    
    Throws:
    
    E - Thrown when this predicate fails.
