Viktor Lofgren 19163fa883 (array) Clean up the Array library
IntArray gets the YAGNI axe.   The array library had two implementations, one for longs which was used, and one for ints, which only ever saw bit rot.   Removing the latter, as all it ever did was clutter up the codebase and add technical debt.  If we need int arrays, we fork LongArray again (or add int capabilities to it)

Also cleaning up the interfaces, removing layers of redundant abstractions and adding javadocs.

Finally adding sz=2 specializations to the quick- and insertion sort algorithms.  It seems the JIT isn't optimizing these particularly well, this is an attempt to help it out a bit.

Libraries

These are libraries that are not strongly coupled to the search engine's business logic. These libraries may not depend on features, services, processes, models, etc.

NOTE: These libraries are co-licensed under the MIT license.

Libraries

  • The array library is for memory mapping large memory-areas, which Java has bad support for. It's designed to be able to easily replaced when Java's Foreign Function And Memory API is released.
  • The btree library offers a static BTree implementation based on the array library.
  • language-processing contains primitives for sentence extraction and POS-tagging.
  • The message-queue library.

Micro libraries

  • easy-lsh is a simple locality-sensitive hash for document deduplication
  • guarded-regex makes predicated regular expressions clearer
  • big-string offers seamless string compression
  • random-write-funnel is a tool for reducing write amplification when constructing large files out of order.
  • next-prime naive brute force prime sieve.
  • braille-block-punch-cards renders bit masks into human-readable dot matrices using the braille block.
