Methods

and(FailableBiPredicate)	Returns a composed FailableBiPredicate like BiPredicate#and(BiPredicate).
falsePredicate()	Gets the FALSE singleton.
negate()	Returns a predicate that negates this predicate.
or(FailableBiPredicate)	Returns a composed FailableBiPredicate like BiPredicate#and(BiPredicate).
test(Object, Object)	Tests the predicate.
truePredicate()	Gets the TRUE singleton.

public 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:

java.lang.NullPointerException – Thrown if other is null.

@SuppressWarnings({"unchecked"}) public static <T, U, E extends Throwable> FailableBiPredicate<T, U, E> falsePredicate()

Gets the FALSE singleton.

Type parameters:

• <T> – Consumed type 1.

• <U> – Consumed type 2.

• <E> – The kind of thrown exception or error.

Returns:

The NOP singleton.

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

Returns a predicate that negates this predicate.

Returns:

A predicate that negates this predicate.

public 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:

java.lang.NullPointerException – Thrown if other is null.

public abstract 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.

@SuppressWarnings({"unchecked"}) public static <T, U, E extends Throwable> FailableBiPredicate<T, U, E> truePredicate()

Gets the TRUE singleton.

Type parameters:

• <T> – Consumed type 1.

• <U> – Consumed type 2.

• <E> – The kind of thrown exception or error.

Returns:

The NOP singleton.
