Subject [jira] [Created] (LUCENE-4120) FST should use packed integer arrays
Date Fri, 08 Jun 2012 09:12:22 GMT
Adrien Grand created LUCENE-4120:

             Summary: FST should use packed integer arrays
                 Key: LUCENE-4120
             Project: Lucene - Java
          Issue Type: Improvement
          Components: core/FSTs
    Affects Versions: 5.0
            Reporter: Adrien Grand
            Priority: Minor
             Fix For: 5.0

There are some places where an int[] could be advantageously replaced with a packed integer

I am thinking (at least) of:
 * FST.nodeAddress (GrowableWriter)
 * FST.inCounts (GrowableWriter)
 * FST.nodeRefToAddress (read-only Reader)

The serialization/deserialization methods should be modified too in order to take advantage
of PackedInts.get{Reader,Writer}.
