Cloneable classes can use their class in the clone() function
-------------------------------------------------------------
Key: LUCENE-3933
URL: https://issues.apache.org/jira/browse/LUCENE-3933
Project: Lucene - Java
Issue Type: Improvement
Reporter: Ryan McKinley
Assignee: Ryan McKinley
Priority: Trivial
Since Java5, we are allowed to use an explicit class when returning clone()
It is nicer to use:
{code:java}
OpenBitSet copy = original.clone();
{code}
then
{code:java}
OpenBitSet copy = (OpenBitSet)original.clone();
{code}
