[jira] Moved: (VALIDATOR-256) StringUtils.isText to check in a null
safe way if a String has (real) text
[ https://issues.apache.org/jira/browse/VALIDATOR-256?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Henri Yandell moved LANG-409 to VALIDATOR-256:
----------------------------------------------
Key: VALIDATOR-256 (was: LANG-409)
Project: Commons Validator (was: Commons Lang)

> I used something similar from the Spring Framework and it was useful. I suggest two methods where the second is a little more advanced then theirs.
> First a method StringUtils.isText(String text) : boolean which checks if the String is not null and contains a least one not whitespace character. (In Spring it's "hasText", but "isText" seams to be more consistent within commons lang.)
> The second method could be StringUtils.isText(String text, int n) : boolean which checks if the String is not null and contains a least n not whitespace characters.
> Question: What happens if a (stupid ;-) developer checks for -5 characters? I think it should throw an IllegalArgumentException.
