Hashtable based Document
------------------------
Key: LUCENE-671
URL: http://issues.apache.org/jira/browse/LUCENE-671
Project: Lucene - Java
Issue Type: Improvement
Components: Index, Search
Affects Versions: 2.0.0, 1.9
Reporter: Chris
Priority: Minor
I've attached a Document based on a hashtable and a performance test case. It
performs better in most cases (all but enumeration by my measurement), but
likely uses a larger memory footprint. The Document testcase will fail since it
accesses the "fields" variable directly and gets confused when it's not the
list it expected it to be.
If nothing else we would be interested in at least being able to extend
Document, which is currently declared final. (Anyone know the performance gains
on declaring a class final?) Currently we have to maintain a copy of lucene
which has methods and classes definalized and overriden.
There are other classes as well that could be declared non-final (Fieldable
comes to mind) since it's possible to make changes for project specific
situations in those aswell but that's off-topic.
