Class Summary
Class	Description
AbstractKeyValue<K,V>	Abstract pair class to assist with creating `KeyValue` and `Map.Entry` implementations.
AbstractMapEntry<K,V>	Abstract Pair class to assist with creating correct `Map.Entry` implementations.
AbstractMapEntryDecorator<K,V>	Provides a base decorator that allows additional functionality to be added to a `Map.Entry`.
DefaultKeyValue<K,V>	A mutable `KeyValue` pair that does not implement `Map.Entry`.
DefaultMapEntry<K,V>	A restricted implementation of `Map.Entry` that prevents the `Map.Entry` contract from being broken.
MultiKey<K>	A `MultiKey` allows multiple map keys to be merged together.
TiedMapEntry<K,V>	A `Map.Entry` tied to a map underneath.
UnmodifiableMapEntry<K,V>	A `Map.Entry` that throws UnsupportedOperationException when `setValue` is called.

Package org.apache.commons.collections4.keyvalue Description

This package contains implementations of collection and map related key/value classes. These are usually used in maps, however they can be used as data holders in any collection.

The following key/value designs are included:

Map Entry - various map entry implementations
KeyValue - a key and value pair, without map entry semantics
MultiKey - a holder of multiple keys tied together
