Mark Miller updated LUCENE-831:
-------------------------------
Attachment: LUCENE-831.patch
Updated to trunk.
I've combined all of the dual (primitive array/ObjectArray) CachKeys into one.
Each cache key can support both modes or throw UnsupportedException or
something.
I've also tried something a bit experimental to allow users to eventually use
custom or alternate cachekeys (payload or sparse arrays or something) that work
with internal sorting. A cache implementation can now supply a
ComparatorFactory (name will prob be tweaked) that handles creating
comparators. You can subclass ComparatorFactory and add new or override current
supported CacheKeys.
CustomComparators still needs to be twiddled with some.
I've converted some of the sort tests to run with both primitive and object
arrays as well.

> Motivation:
> 1) Complete overhaul the API/implementation of "FieldCache" type things...
> a) eliminate global static map keyed on IndexReader (thus
> eliminating synch block between completley independent IndexReaders)
> b) allow more customization of cache management (ie: use
> expiration/replacement strategies, disk backed caches, etc)
> c) allow people to define custom cache data logic (ie: custom
> parsers, complex datatypes, etc... anything tied to a reader)
> d) allow people to inspect what's in a cache (list of CacheKeys) for
> an IndexReader so a new IndexReader can be likewise warmed.
> e) Lend support for smarter cache management if/when
> IndexReader.reopen is added (merging of cached data from subReaders).
> 2) Provide backwards compatibility to support existing FieldCache API with
> the new implementation, so there is no redundent caching as client code
> migrades to new API.
