Class Range

java.lang.Object
  ubiware.util.Range

All Implemented Interfaces:

java.lang.Iterable<java.lang.Integer>

public class Range
extends java.lang.Object
implements java.lang.Iterable<java.lang.Integer>

Implementation which mimics the Python range class. It offers an iterable object which returns integers Use as follows:

 for (Integer i : new Range(start, end, step){
                //do something  with the integer
 }

Constructor Summary

Range(int end)
Same as Range(int, int, int) with start set to 0 and step set to 1

Range(int start, int end)
Same as Range(int, int, int) with start set to start and step set to 1

Range(int start, int end, int step)
Create an Iterable which returns an Iterator which produces a series of integers where the first element = start then n-th element = n-1 th element + step The iteration stops before the integer would become greater as end.

Range

public Range(int start,
             int end,
             int step)

Create an Iterable which returns an Iterator which produces a series of integers where

• the first element = start
• then n-th element = n-1 th element + step
• The iteration stops before the integer would become greater as end.

Parameters:

start - the first element

end - limit

step - the step between every returned element.
