Class FilteredComparator<M>

java.lang.Object

edu.stanford.math.plex4.streams.utility.FilteredComparator<M>

Type Parameters:

M - the underlying type of the basis elements

All Implemented Interfaces:

java.util.Comparator<M>

public class FilteredComparator<M>
extends java.lang.Object
implements java.util.Comparator<M>

This class provides filtration based comparison of basis elements. It implements a dictionary ordering where first the filtration indices are compared, and then the actual basis elements are compared using the supplied comparator.
