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. > StringUtils.isText to check in a null safe way if a String has (real) text > -------------------------------------------------------------------------- > > Key: LANG-409 > URL: https://issues.apache.org/jira/browse/LANG-409 > Project: Commons Lang > Issue Type: Improvement > Reporter: Jörg Gottschling > Priority: Minor > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
