Alexander Tsvetkov commented on LANG-1412:
------------------------------------------
I can contribute this feature to https://github.com/apache/commons-lang/ if you
see any value in it and are willing to review it. :)
> Add toArray method to CharSet
> -----------------------------
>
> Key: LANG-1412
> URL: https://issues.apache.org/jira/browse/LANG-1412
> Project: Commons Lang
> Issue Type: New Feature
> Reporter: Alexander Tsvetkov
> Priority: Major
>
> We have a project where we generate a random string from a set of legal
> characters like this:
> {code:java}
> StringBuilder stringBuilder = new StringBuilder(length);
> for (int i = 0; i < length; i++) {
> int randomIndex = randomGenerator.nextInt(LEGAL_CHARACTERS.length);
> stringBuilder.append(LEGAL_CHARACTERS[randomIndex]);
> }
> return stringBuilder.toString();
> {code}
> Where LEGAL_CHARACTERS is a char array. The problem is that initializing the
> LEGAL_CHARACTERS array is not very pretty and we would like to do it this way:
> {code:java}
> private static final char[] LEGAL_CHARACTERS = CharSet.getInstance("A-Z",
> "a-z", "0-9", "-", "_@()&#*[]").toArray();
> {code}
> Do you think this would be a good addition to Commons Lang in general? If
> yes, then is CharSet the right place for that?
