Mike Drob created ACCUMULO-2486: ----------------------------------- Summary: Use covariant return types in SKVI.deepCopy Key: ACCUMULO-2486 URL: https://issues.apache.org/jira/browse/ACCUMULO-2486 Project: Accumulo Issue Type: Improvement Reporter: Mike Drob Fix For: 1.7.0
Starting with Java 5, subclasses with method overrides can declare covariant return types. In general, I believe that we want to do this, as it provides stronger type guarantees with not a lot of extra cost. Example: {code} public interface SortedKeyValueIterator { SortedKeyValueIterator deepCopy(IteratorEnvironment env); } public interface InterruptibleIterator extends SortedKeyValueIterator { @Override InterruptibleIterator deepCopy(IteratorEnvironment env); } {code} I believe this change will be fully backwards compatible with the existing APIs. -- This message was sent by Atlassian JIRA (v6.2#6252)
