Subject [jira] Updated: (LANG-424) Improve Javadoc for StringUtils class
Date Sun, 11 May 2008 06:07:55 GMT


Henri Yandell updated LANG-424:

    Fix Version/s: 3.0

> Improve Javadoc for StringUtils class
> -------------------------------------
>                 Key: LANG-424
>                 URL:
>             Project: Commons Lang
>          Issue Type: Improvement
>    Affects Versions: 2.4
>            Reporter: Denise Fernandez
>             Fix For: 3.0
> In the StringUtils class it would be helpful if in the following methods, the Javadoc
is improved:
> substringAfter
> substringAfterLast
> I think there should be better documentation in the case where the separator string is
not found in the search string: It should be explicity noted that in this case an empty string
will be returned.
> In the following methods:
> substringBefore
> substringBeforeLast
> It should be documented that if the separator is not found in the search string, the
search string is returned.
> I realise there are examples for both these cases, but I think that they should be separately
and explicity documented as special cases. I had expected that substringAfterLast would return
the original string if the separator was not found in it and this caused me some trouble.
