Subject [jira] [Commented] (LUCENE-3590) minimize bytesref to be a ref to a byte[]
Date Thu, 24 Nov 2011 14:38:41 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3590?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13156728#comment-13156728

Robert Muir commented on LUCENE-3590:
-------------------------------------

First step is to remove the ctor BytesRef(BytesRef other), which is not intuitive
since it looks like a copy constructor, but doesn't copy the ref, it creates 
a brand new byte array pointing to a complete copy of 'other's bytes, and then
creates a pointer to that.

I think its not obvious from the code either when i see new BytesRef(otherBytesRef).
Instead we should do:

{copy}
BytesRef copy = new BytesRef();
copy.copyBytes(otherBytesRef);
{copy}

This makes it totally clear exactly what is going on. I'll work up a patch

> Setting this as blocker for 4.0, as this class is used in every API there.
> Currently this API is a little of a everything, sometimes its like a stringbuffer, it
> does numeric conversions, all kinds of stuff.
> We need this to be a ref to a byte[], nothing else. This other stuff can go somewhere
else.
