Subject [jira] Commented: (LANG-409) StringUtils.isText to check in a null safe way if a String has (real) text
Date Tue, 12 Feb 2008 17:35:09 GMT

    [ https://issues.apache.org/jira/browse/LANG-409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12568233#action_12568233
] 

Jörg Gottschling commented on LANG-409:
---------------------------------------

Yes, but mainly with validation of user inputs, I think. I remember just one other case, where
a String had to be at least three 'real' characters long. All other cases where more complex,
like 40 hex chars or something like that.

> 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.
