Simon Kitching commented on LANG-454:
-------------------------------------
Interesting. Several languages (ruby,python,perl) do have similar "iterate over
range" functionality.
If implemented, it would possibly be better to use the "generator" pattern
rather than actually returning a collection, ie return a custom iterator that
knows how to generate the next value instead of creating a real collection.
Sadly due to limitations in java's for-loop, new-style for loops require a
collection object (ie type Iterable) not an iterator though. And probably
c:forEach needs Iterable or Collection too.
Generators or similar do feel more like commons-collections territory than
commons-lang though.

> Key: LANG-454
> URL: https://issues.apache.org/jira/browse/LANG-454
> Project: Commons Lang
> Issue Type: Improvement
> Affects Versions: 2.4
> Reporter: Kenny MacLeod
>
> org.apache.commons.lang.CharRange would be a lot more useful if it had a
> means to obtain the characters in the range as a char array.
> i.e.
> new CharRange('a',''d').toCharArray() == new char[] { 'a', 'b', 'c', 'd' }
