Class Functional.Range

java.lang.Object
  util.Functional.Range

All Implemented Interfaces:

Iterable<Integer>

Enclosing class:

Functional

public static final class Functional.Range
extends Object
implements Iterable<Integer>

An iterable representing a range of integers. Useful for iterating over integers in a foreach loop without using memory for the integers. (However, old-style ugly for loops are still more efficient since they can be done with only primitives.)

Has no public constructors; use Functional.range(int, int) or another such to obtain one.
