Interface ValueSelector<V extends PrismValue>

All Superinterfaces:

Predicate<V>

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 ValueSelector<V extends PrismValue>
extends Predicate<V>

Selects a value from multivalued item (property, container, reference). A typical use is to select among PrismContainerValues by checking some sub-item ("key") value. TODO Find a better name. "ValueMatcher" is already used in a different context.
