Improve Javadoc for StringUtils class
-------------------------------------
Key: LANG-424
URL: https://issues.apache.org/jira/browse/LANG-424
Project: Commons Lang
Issue Type: Improvement
Affects Versions: 2.4
Reporter: Denise Fernandez
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.
