Type Parameters:

T - Predicate type.

E - The kind of thrown exception or error.

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 java.lang.Throwable>
```
A functional interface like Predicate that declares a Throwable.
