Interface Matcher<E>

All Superinterfaces:

java.util.function.Predicate<E>

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 Matcher<E>
extends java.util.function.Predicate<E>

Determines which values should be filtered.

For best safety, implementations of Matcher should be immutable. This guarantees that FilterLists can safely call matches() without synchronization.

As of Glazed Lists 1.12 Matcher was adapted to extend the Predicate interface. This way you can use an existing Matcher everywhere a predicate is expected.

In order to create dynamic filtering, use a MatcherEditor, which can create immutable Matcher Objects each time the matching constraints change.
