Class IndicesRange

  • All Implemented Interfaces:
    Range
    public class IndicesRange
extends java.lang.Object
implements Range
    Range which varies over pre-specified indices. For example, 
         int[] indices = new int[] { 1, 1, 2, 3, 5, 8, 13 };
     Range r = new IndicesRange(indices);
    ranges over the first few Fibonacci numbers.
