Subject [jira] [Commented] (ACCUMULO-2487) Value implementation provides conflicting statements
Date Mon, 17 Mar 2014 21:00:46 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2487?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13938378#comment-13938378

Josh Elser commented on ACCUMULO-2487:
--------------------------------------

I agree on a 1.6.0 fix as this has bitten me before. I don't think #2 is a big deal to me
-- if the user happens to give the byte[] variant an array of size 0, so what. Having the
concise version which operates as was initially intended is good IMO.

> The javadoc for the no-arg constructor for {{Value}} states that it "Creates a zero-size
sequence." However, the implementation of get will error in this case.
> {code}
> public byte[] get() {
>     if (this.value == null) {
>       throw new IllegalStateException("Uninitialized. Null constructor " + "called w/o
accompanying readFields invocation");
>     }
> {code}
> Either we need to change the javadoc to be more explicit or change the behaviour of various
accessors in the class. I would consider both solutions to be breaking of the API contract
since we are changing what clients can expect from us.
