[jira] Commented: (LUCENE-2589) Add a variable-sized int block
codec
[ https://issues.apache.org/jira/browse/LUCENE-2589?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12896397#action_12896397 ]
Simon Willnauer commented on LUCENE-2589:
-----------------------------------------
bq. Simple patch - uses regexp to parse out a single int param.
Looks good to me - makes sense to have the size configurable. I wonder if we should start some documentation either in src/test/../package.html or on the wiki which holds information about how we test and which properties are recognized in the unit test.
Thoughts?

> We already have support for fixed block size int block codecs, making it very simple to create a codec from a int encoder algorithms like FOR/PFOR.
> But algorithms like Simple9/16 are not fixed -- they encode a variable number of adjacent ints at once, depending on the specific values of those ints.
