[jira] Commented: (LUCENE-2189) Simple9 (de)compression

["Michael McCandless (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-2189?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12895283#action_12895283 ] 

Michael McCandless commented on LUCENE-2189:
--------------------------------------------

It'd be best if the interface to Simple9/16 (and in general any variable sized int block encoder that we can tap into as a codec) were an incremental one.

EG I could instantiate the encoder, then call .add(int value) to add a new value, which'd return maybe a boolean indicating that a new output block has been flushed/created as a result of adding that value.

I'm trying to make a simple-to-reuse variable sized int block codec where we could just drop in Simple9/16/etc, and this incremental API would work well for this.
