Class RangeGenerator

java.lang.Object
  net.ericaro.neoitertools.generators.RangeGenerator

All Implemented Interfaces:

Generator<java.lang.Integer>

public class RangeGenerator
extends java.lang.Object
implements Generator<java.lang.Integer>

This is a versatile Generator containing arithmetic progressions. It is most often used in for loops. The full form returns an iterator over Integers [start, start + step, start + 2 * step, ...].

• If step is positive, the last element is the largest start + i * step less than stop;
• if step is negative, the last element is the smallest start + i * step greater than stop.
• step must not be zero (or else InvalidParameterException is raised).
