-/**
- * Interface for objects that specify an ordering between objects. The ordering
- * should be total, such that any two objects of the correct type
- * can be compared, and the comparison is reflexive, anti-symmetric, and
- * transitive. It is also recommended that the comparator be consistent
- * with equals, although this is not a strict requirement. A relation
- * is consistent with equals if these two statements always have the same
- * results (if no exceptions occur):
- * compare((Object) e1, (Object) e2) == 0
and
- * e1.equals((Object) e2)
- * Comparators that violate consistency with equals may cause strange behavior
- * in sorted lists and sets. For example, a case-sensitive dictionary order
- * comparison of Strings is consistent with equals, but if it is
- * case-insensitive it is not, because "abc" and "ABC" compare as equal even
- * though "abc".equals("ABC") returns false.
- *
- * In general, Comparators should be Serializable, because when they are passed
- * to Serializable data structures such as SortedMap or SortedSet, the entire
- * data structure will only serialize correctly if the comparator is
- * Serializable.
- *
- * @author Original author unknown
- * @author Eric Blake
- *
- * Although it is permissible for a comparator to provide an order
- * inconsistent with equals, that should be documented.
- *
- * @param o1 the first object
- * @param o2 the second object
- * @return the comparison
- * @throws ClassCastException if the elements are not of types that can be
- * compared by this ordering.

- int compare(Object o1, Object o2);

- /**
- * Return true if the object is equal to this object. To be
- * considered equal, the argument object must satisfy the constraints
- * of
- *
- *
Object.equals()
, be a Comparator, and impose the
- * same ordering as this Comparator. The default implementation
- * inherited from Object is usually adequate.
- *
- * @param obj The object
- * @return true if it is a Comparator that imposes the same order
