Class IloLexicographicComparator<>

A lexicographic comparator is a composite comparator, CC, made of an ordered set O, of comparators ci. The result of comparing two objects o1 and o2 with CC, denoted CC(o1, o2), is as follows:

 CC(o1, o2) = 0
        if for all i, ci(o1, o2) = 0, ci element 0

 CC(o1, o2) = ci(o1, o2)
      if ci(o1, o2) != 0 AND
        for all j < i cj(o1, o2) = 0,
         ci, cj element 0
 

The function IloCompositeComparator::add is available to build a comparator by addition rather than by specifying all comparators at construction time.

For more information, see Selectors.

This constructor intializes an empty lexicographic comparator allocated on the memory manager manager.
