Compares two RealTuple-s of the same RealTupleType.

Specified by:

compare in interface Comparator

Parameters:

obj1 - The first RealTuple.

obj2 - The second RealTuple. It shall have the same RealTupleType as the first RealTuple.

Returns:

A negative integer, zero, or a positive integer as the first RealTuple is less than, equal to, or greater than the second RealTuple.
