---------------------------------------

             Summary: Avoid looping over merge segments in best merge selection
                 Key: LUCENE-7915
                 URL: https://issues.apache.org/jira/browse/LUCENE-7915
             Project: Lucene - Core
          Issue Type: Improvement
          Components: core/index
            Reporter: Tommaso Teofili
            Assignee: Tommaso Teofili
            Priority: Trivial
             Fix For: trunk


With java 8 we can trivially avoid looping over merge segments to be merged, switching from

{code}
for(SegmentCommitInfo info : merge.segments) {
  toBeMerged.add(info);
}
{code}

to :

{code}
toBeMerged.addAll(merge.segments);
{code}
