Class RangePermutator

java.lang.Object

etomica.graph.iterators.RangePermutator

All Implemented Interfaces:

Permutator, java.util.Iterator<byte[]>

public class RangePermutator
extends java.lang.Object
implements Permutator

This is a facility class that iterates through (maxP1 - minP1 + 1) permutations one at a time. When the last element of the K-th permutation is produced, the next element is the first element of the (K+1)-th permutation. Each permutation iteration consists of two classes with a fixed total number of elements. For example, an instance of this class created as new PermutationRangeIterator(8, 0, 8) would generate all combinations of 8 bits.
