etomica.lattice.IndexIteratorIncreasing

public class IndexIteratorIncreasing
extends java.lang.Object

Iterator that returns indices in increasing order, starting at 0 and ending including all indices where |i| <= max, where i are the components of the index. This class has the same effect as IndexIteratorReflector + IndexIteratorTriangularPermutations, but is ~15x faster.
