Interface PredicateEx<T>

Type Parameters:

T - the type of the input to the predicate

All Superinterfaces:

Predicate<T>, Serializable

All Known Subinterfaces:

JetMemberSelector

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 PredicateEx<T>
extends Predicate<T>, Serializable

Serializable variant of java.util.function.Predicate which declares checked exception.

Since:

4.0
