Interface MultiMapFactory<K,V>

All Superinterfaces:

MapFactory<K,V>

All Known Implementing Classes:

GenericMultiMapFactory, PersistentMultiMapFactory

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 MultiMapFactory<K,V>
extends MapFactory<K,V>

MultiMapFactory is a MultiMap generator. Implementations construct specific types of MultiMaps. It is a functional interface, whose method is makeMultiMap(), so a constructor of an empty MultiMap is a MultiMapFactory: GenericMultiMap::new.
