Package org.apache.commons.collections.keyvalue
This package contains implementations of collection and map related key/value classes.
AbstractKeyValue | Abstract pair class to assist with creating KeyValue and MapEntry implementations. |
AbstractMapEntry | Abstract Pair class to assist with creating correct Map Entry implementations. |
AbstractMapEntryDecorator | Provides a base decorator that allows additional functionality to be added
to a Map Entry. |
DefaultKeyValue | A mutable KeyValue pair that does not implement MapEntry. |
DefaultMapEntry | A restricted implementation of java.util.Map.Entry that prevents
the MapEntry contract from being broken. |
MultiKey | A MultiKey allows multiple map keys to be merged together. |
TiedMapEntry | A Map Entry tied to a map underneath. |
UnmodifiableMapEntry | A java.util.Map.Entry that throws UnsupportedOperationException
when setValue is called. |
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
