The Eclipse Collections project provides object and primitive data structures for Java (e.g. List, Set, Bag, Multimap, BiMap, Stack). New container implementations, new iteration protocols, additional parallel iteration patterns and types may be added over time but they should extend one of the root types like RichIterable, PrimitiveIterable or ParallelIterable.
