and

default FailableBiPredicate<T,U,E> and(FailableBiPredicate<? super T,? super U,E> other)

Returns a composed FailableBiPredicate like BiPredicate.and(BiPredicate).

Parameters:

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

Returns:

a composed FailableBiPredicate like BiPredicate.and(BiPredicate).

Throws:

NullPointerException - if other is null

negate

default FailableBiPredicate<T,U,E> negate()

a predicate that negates this predicate.

or

default FailableBiPredicate<T,U,E> or(FailableBiPredicate<? super T,? super U,E> other)

Returns a composed FailableBiPredicate like BiPredicate.and(BiPredicate).

Parameters:

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

Returns:

a composed FailableBiPredicate like BiPredicate.and(BiPredicate).

Throws:

NullPointerException - if other is null

test

boolean test(T object1,
 U object2)
      throws E

Tests the predicate.

Parameters:

object1 - the first object to test the predicate on

object2 - the second object to test the predicate on

Returns:

the predicate's evaluation

Throws:

E - Thrown when this predicate fails.
