Interface UncheckedPredicate<T>

Type Parameters:

T - the type of the input to the predicate

All Superinterfaces:

java.util.function.Predicate<T>

All Known Implementing Classes:

AnyTypesPredicate

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 UncheckedPredicate<T>
extends java.util.function.Predicate<T>

Operations that throw RepositoryException cannot be used as lambdas without "unchecking" those exceptions.

Method Detail

test

default boolean test(T elem)

Specified by:

test in interface java.util.function.Predicate<T>

testThrows

boolean testThrows(T elem)
            throws javax.jcr.RepositoryException

The same semantic as test(Object), but allowed to throw a RepositoryException

Parameters:

elem - the input argument

Returns:

true if the input matches the predicate, otherwise false

Throws:

javax.jcr.RepositoryException - a repository-related exception

uncheck

static <T> UncheckedPredicate<T> uncheck(UncheckedPredicate<T> p)

Type Parameters:

T - the type of the input to the predicate

Parameters:

p - a lambda expression

Returns:

an unchecked version of that lambda
