Adrien Grand resolved LUCENE-4239. ---------------------------------- Resolution: Fixed Done has part of LUCENE-3892 which was just merged to trunk (r1375486). > Provide access to PackedInts' low-level blocks <-> values conversion methods > ---------------------------------------------------------------------------- > > Key: LUCENE-4239 > URL: https://issues.apache.org/jira/browse/LUCENE-4239 > Project: Lucene - Core > Issue Type: Improvement > Components: core/other > Reporter: Adrien Grand > Assignee: Adrien Grand > Priority: Minor > Fix For: 4.0 > > Attachments: LUCENE-4239.patch > > > In LUCENE-4161 we started to make the {{PackedInts}} API more flexible so > that codecs could use it whenever they need to (un)pack integers. There are > two posting formats in progress (For and PFor, LUCENE-3892) that perform a > lot of integer (un)packing but the current API still has limits : > - it only works with long[] arrays, whereas these codecs need to manipulate > int[] arrays, > - the packed reader iterators work great for unpacking long sequences of > integers, but they would probably cause a lot of overhead to decode lots of > short integer sequences such as the ones that can be generated by For and > PFor. > I've been looking at the For/PFor branch and it has a > {{PackedIntsDecompress}} class > (http://svn.apache.org/repos/asf/lucene/dev/branches/pforcodec_3892/lucene/core/src/java/org/apache/lucene/codecs/pfor/PackedIntsDecompress.java) > which is very similar to {{oal.util.packed.BulkOperation}} > (package-private), so maybe we should find a way to expose this class so that > the For/PFor branch can directly use it. -- This message is automatically generated by JIRA.
