Subject [jira] [Commented] (LUCENE-4285) Improve FST API usability for mere mortals
Date Sat, 06 Oct 2012 18:33:02 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4285?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13471081#comment-13471081

David Smiley commented on LUCENE-4285:
--------------------------------------

I admit checked exceptions would have alerted me to my bug, but that doesn't make the API
any nicer -- I still need null checks littered through my FST user code now.  I don't know
the FST internals but I'd be surprised to hear that adding support for an empty FST adds appreciable
overhead.  If this "overhead" we're discussing is a simple conditional check, then this is
net-zero since as it is I need these null checks on my end of the API due to my FST being
potentially null.

> FST technology is something that has brought amazing advances to Lucene, yet the API
is hard to use for the vast majority of users like me.  I know that performance of FSTs is
really important, but surely a lot can be done without sacrificing that.
