    All Implemented Interfaces:

    public class LopComparator<N extends Lop>

    implements Comparator<N>
    Comparator class used in sorting the LopDAG in topological order. Refer to doTopologicalSort_strict_order() in dml/lops/compile/ Topological sort guarantees the following: 1) All lops with level i appear before any lop with level greater than i (source nodes are at level 0) 2) Within a given level, nodes are ordered by their ID i.e., by the other in which they are created compare() method is designed to respect the above two requirements.
