This release provides the following major improvements.

  • Sorted map, JImmutables.sortedMap(), implementation changed to use a B-Tree instead of a 2-3 Tree. The B-Tree implementation offers better performance and simpler code.
  • Hash map, JImmutables.map(), implementation changed to use a simpler HAMT implementation that stores values inside interior nodes as well as in leaf nodes. The new implementation offers significant performance improvements and some memory savings.
  • Sparse array, JImmutables.array(), implementation simplified by removing the extra methods previously used by hash maps.
  • All collections now implement Serializable interface.
  • All collections now provide methods to create Stream Collector implementations that can be used to construct collections directly from a Stream.

More information about the new maps is available in a blog post.
