Interface ThrowingBiPredicate<T,U,E extends Exception>

Type Parameters:

T - the type of the first argument to the predicate

U - the type of the second argument to the predicate

E - the type of the thrown checked 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 ThrowingBiPredicate<T,U,E extends Exception>

Represents a predicate (boolean-valued function) of two arguments. This is the two-arity specialization of ThrowingPredicate. Function may throw a checked exception.

Method Detail

test

boolean test(T t,
             U u)
      throws E extends Exception

Throws:

E extends Exception

unchecked

static <T,U> BiPredicate<T,U> unchecked(ThrowingBiPredicate<T,U,?> predicate)

sneaky

static <T,U> BiPredicate<T,U> sneaky(ThrowingBiPredicate<T,U,?> predicate)

Returns:

BiPredicate instance that rethrows the checked exception using the Sneaky Throws pattern

and

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

or

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

xor

default ThrowingBiPredicate<T,U,E> xor(ThrowingBiPredicate<? super T,? super U,? extends E> other)

negate

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

asFunction

default ThrowingBiFunction<T,U,Boolean,E> asFunction()

Returns:

this ThrowingBiFunction instance as a ThrowingBiFunction

uncheck

default BiPredicate<T,U> uncheck()

Returns:

a new BiPredicate instance which wraps thrown checked exception instance into a RuntimeException
