Subject [jira] [Commented] (ACCUMULO-2619) Review use of Cloneable
Date Thu, 03 Apr 2014 08:49:19 GMT


Sean Busbey commented on ACCUMULO-2619:

I'd like feedback on target version for fixing this. Presuming any of the clone() methods
in the public API can be removed, I'd kind of like to find time to deprecate them for the
1.6.0 release so that they can be removed in the next major version.

>             Project: Accumulo
>          Issue Type: Improvement
>            Reporter: Sean Busbey
>            Priority: Minor
> We have a few places that claim cloneable, including in the public API. Go through and
bring them in line with Effective  Java.
> Note that this means where possible we should favor a copy constructor to using the clone
method, since it is fundamentally broken.
> Where we must have it we need to make sure we obey all the rules.
> # return the type of the class implementing Cloneable
> # do not throw CloneNotSupportedException
> # make sure to return the result of super.clone() (unless the class is final)
> # any fields that are not safe to share between an object and its clone must be deep
copied after using super.clone().
