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
