FailableDoublePredicate (Apache Commons Lang 3.12.0 API)

Type Parameters:

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 FailableDoublePredicate<E extends Throwable>
```
A functional interface like DoublePredicate that declares a Throwable.

    Parameters:
    
    other - a predicate that will be logically-ORed with this predicate.
    
    Returns:
    
    a composed FailableDoublePredicate like DoublePredicate.and(DoublePredicate).
    
    Throws:
    
    NullPointerException - if other is null
  - test
```
boolean test(double value)
      throws E extends Throwable
```
    Tests the predicate.
    
    Parameters:
    
    value - the parameter for the predicate to accept.
    
    Returns:
    
    true if the input argument matches the predicate, false otherwise.
    
    Throws:
    
    E - Thrown when the consumer fails.
