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
