The NOP singleton.

and

default FailableDoublePredicate<E> and(FailableDoublePredicate<E> other)

Returns a composed FailableDoublePredicate like DoublePredicate.and(DoublePredicate).

Parameters:

other - a predicate that will be logically-ANDed with this predicate.

Returns:

a composed FailableDoublePredicate like DoublePredicate.and(DoublePredicate).

Throws:

NullPointerException - if other is null

negate

default FailableDoublePredicate<E> negate()

Returns a predicate that negates this predicate.

Returns:

a predicate that negates this predicate.

or

default FailableDoublePredicate<E> or(FailableDoublePredicate<E> other)

Returns a composed FailableDoublePredicate like DoublePredicate.and(DoublePredicate).

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

Tests the predicate.

Parameters:

value - the parameter for the predicate to accept.

Returns:

true if the input argument matches the predicate, false otherwise.
