Class ComparatorChain

java.lang.Object

etomica.graph.model.comparators.ComparatorChain

All Implemented Interfaces:

java.util.Comparator<Graph>

public class ComparatorChain
extends java.lang.Object
implements java.util.Comparator<Graph>

Comparator class that can chain together a list of comparators. The first comparator that recognizes one graph as coming before another is used. If none of the comparators gives precedence to one of the graphs, this class falls back to the Graph's internal comparison, and then the hashCode.

Method Detail

addComparator

public void addComparator(java.util.Comparator<Graph> comparator)

Add a comparator that will be used to sort sort graphs. Comparators will be used in the order in which they are added; later comparators will be used only if earlier comparators return 0.

addReverseComparator

public void addReverseComparator(java.util.Comparator<Graph> comparator)

Add a comparator that will be used to sort sort graphs in reverse order.

compare

public int compare(Graph g1,
                   Graph g2)
