ExportTable.isReady - alternative to for loop?
David Medinets 2012-09-06, 02:20
This is the code I am looking at:

    // TODO look for walogs
    for (Entry<Key,Value> entry : metaScanner) {
      return 500;
    }

    return 0;

FindBugs complains that entry is unused. Does it make sense to replace
that code with:

  return metaScanner.iterator().hasNext() ? 500 : 0;
