[jira] Commented: (LANG-425) Sequence(String)Utils

["Henri Yandell (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LANG-425?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12727131#action_12727131 ] 

Henri Yandell commented on LANG-425:
------------------------------------

Coming back to this....

I don't think nextInt has much value (x++) or nextBoolean (!bool). Which matches the focus above on StringSequence.

It's a bit of a mix between the text.translate package and the CharSetUtils class in some ways. 

Some hypothetical ways to implement a hex number counter:

UnicodeSequence.between(0x30, 0x39).andBetween(0x41, 0x46)

or:

CharSequence.iterator("0-9A-F")

>             Project: Commons Lang
>          Issue Type: Wish

>            Priority: Trivial

> Don't you think it's kind of strange to have RandomUtils and RandomStringUtils, but not just the ordinairy SequenceUtils?
> I've seen commons-id in the sandbox, but maybe some basics should become part of commons lang.
> Most classes of within this package are stateless/static, or they have a state within a method (such as StrBuilder). SequenceUtils can only be static, if it has the startValue.
> For example
> {code}
> SequenceUtils.nextInt(10)
> SequenceUtils.nextString("MORE")
> SequenceUtils.nextBoolean(true) //ok, this one is stupid but quite clear
> SequenceUtils.nextString("C0DE", "0123456789ABCDEF") //next hexadecimal
> {code}
> any more ideas?
