[jira] Commented: (CASSANDRA-1252) @Override annotation on implementing methods

["Folke Behrens (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-1252?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12885610#action_12885610 ] 

Folke Behrens commented on CASSANDRA-1252:
------------------------------------------

Dude, get a copy and read the entire Item 36. Yes, he writes that @Override is unnecessary for implementing methods because the compiler will warn you if signatures don't match but he also wrote an entire page about why it is still a good idea to do it anyway.

> The current [CodeStyle|http://wiki.apache.org/cassandra/CodeStyle] states that one should "avoid redundant @Override annotations when implementing abstract or interface methods." A rationale is not given.
> The @Override annotation is not redundant. When putting it on implementing methods it helps detecting abstract methods of super-classes or interfaces that were removed. This is especially important when extending abstract classes or implementing interfaces from external libraries.
> Please tag every overriding method with @Override and make compiler warnings errors.
