NAME

Range::Iterator - Generate an iterator object for range

VERSION

This document describes version 0.002 of Range::Iterator (from Perl distribution Range-Iterator), released on 2019-04-23.

SYNOPSIS

  use Range::Iterator;

  my $iter = Range::Iterator->new(1, 10);
  while (defined(my $val = $iter->next)) { ... } # 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

You can add step:

 my $iter = Range::Iterator->new(1, 10, 2); # 1, 3, 5, 7, 9

You can use alphanumeric strings too since ++ has some extra builtin magic (see perlop):

 $iter = Range::Iterator->new("zx", "aab"); # zx, zy, zz, aaa, aab

Infinite list:

 $iter = Range::Iterator->new(1, Inf); # 1, 2, 3, ...

DESCRIPTION

This module offers an object-based iterator for range.

METHODS

new

Usage:

 $obj = Range::Iterator->new($start, $end [ , $step ])

next
