Method Details

test

boolean test(T t)
      throws E

Throws:

E

unchecked

static <T> Predicate<T> unchecked(ThrowingPredicate<T,?> predicate)

sneaky

static <T> Predicate<T> sneaky(ThrowingPredicate<T,?> predicate)

Returns:

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

and

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

or

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

xor

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

negate

default ThrowingPredicate<T,E> negate()

asFunction

default ThrowingFunction<T,Boolean,E> asFunction()

Returns:

this Predicate instance as a Function instance

uncheck

default Predicate<T> uncheck()

Returns:

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