Subject [jira] [Created] (LUCENE-3360) Move FieldCache to IndexReader
Date Thu, 04 Aug 2011 08:51:27 GMT
Move FieldCache to IndexReader

                 Key: LUCENE-3360
             Project: Lucene - Java
          Issue Type: Improvement
            Reporter: Martijn van Groningen
             Fix For: 4.0

Move the static FieldCache.DEFAULT field instance to atomic IndexReaders, so that FieldCache
insanity caused by the WeakHashMap no longer occurs.
* Add a new method to IndexReader that by default throws an UOE:
{code}public FieldCache getFieldCache(){code}
* The SegmentReader implements this method and returns its own internal FieldCache implementation.
This implementation just uses a HashMap<Entry<T>,Object>> to store entries.
* The SlowMultiReaderWrapper implements this method as well and basically behaves the same
as the current FieldCacheImpl.

This issue won't solve the insanity that comes from inconsistent usage of a single field (for
example retrieve both int[] and DocTermIndex for the same field).
