Usage

From source file:ch.ledcom.log4jtools.utils.FilenameComparator.java

@Override
public final int compare(File f1, File f2) {
    DateTime d1 = ParseUtils.extractDateFromName(f1);
    Integer s1 = ParseUtils.extractSequenceFromName(f1);
    DateTime d2 = ParseUtils.extractDateFromName(f2);
    Integer s2 = ParseUtils.extractSequenceFromName(f2);

    if (ObjectUtils.compare(d1, d2, true) == 0) {
        return ObjectUtils.compare(s1, s2, true);
    }//from   ww w .  j  a va2 s  .  c om
    return ObjectUtils.compare(d1, d2, true);
