Class Summary
Class	Description
AbstractListValuedMap<K,V>	Abstract implementation of the `ListValuedMap` interface to simplify the creation of subclass implementations.
AbstractMultiValuedMap<K,V>	Abstract implementation of the `MultiValuedMap` interface to simplify the creation of subclass implementations.
AbstractMultiValuedMapDecorator<K,V>	Decorates another `MultiValuedMap` to provide additional behaviour.
AbstractSetValuedMap<K,V>	Abstract implementation of the `SetValuedMap` interface to simplify the creation of subclass implementations.
ArrayListValuedHashMap<K,V>	Implements a `ListValuedMap`, using a `HashMap` to provide data storage and `ArrayList`s as value collections.
HashSetValuedHashMap<K,V>	Implements a `SetValuedMap`, using a `HashMap` to provide data storage and `HashSet`s as value collections.
TransformedMultiValuedMap<K,V>	Decorates another `MultiValuedMap` to transform objects that are added.
UnmodifiableMultiValuedMap<K,V>	Decorates another `MultiValuedMap` to ensure it can't be altered.

Package org.apache.commons.collections4.multimap Description

This package contains implementations of the MultiValuedMap interfaces. A MultiValuedMap holds a collection of values against each key.

The following implementations are provided in the package:

ArrayListValuedHashMap - ListValuedMap implementation using a HashMap/ArrayList
HashSetValuedHashMap - SetValuedMap implementation using a HashMap/HashSet

The following decorators are provided in the package:

Transformed - transforms elements added to the MultiValuedMap
Unmodifiable - ensures the collection cannot be altered
