Type Parameters:

T - Predicate type.

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 FailablePredicate<T,E extends Throwable>
```
A functional interface like Predicate that declares a Throwable.

default FailablePredicate<T,E> or(FailablePredicate<? super T,E> other)
```
    Returns a composed FailablePredicate like Predicate.and(Predicate).
    
    Parameters:
    
    other - a predicate that will be logically-ORed with this predicate.
    
    Returns:
    
    a composed FailablePredicate like Predicate.and(Predicate).
    
    Throws:
    
    NullPointerException - if other is null
  - test
```
boolean test(T object)
      throws E extends Throwable
```
    Tests the predicate.
    
    Parameters:
    
    object - the object to test the predicate on
    
    Returns:
    
    the predicate's evaluation
    
    Throws:
    
    E - if the predicate fails
    
    E extends Throwable
