Subject [jira] Commented: (LANG-619) String prefixing/suffixing
Date Mon, 19 Apr 2010 07:07:50 GMT


Stephan van Hugten commented on LANG-619:

I agree, but my lack of knowledge of regexes was the reason to opt for my approach. I would
like to conclude that these convenience methods are of course null-safe and were useful for
our project. You may decide what to do with it in your project.

>    Affects Versions: 2.5

> I had a use case that I wanted to search through a string and, when I found a match,
prefix or suffix (or both) the matching term, i.e. to apply a highlighting class to a matching
keyword in a search.
> I noticed that this cannot be done by the StringUtils framework, so me and a colleague
made this code and would like to donate it to the StringUtils project. In the attachment I
included the class with the extensions plus a Unit test testing all the usecases. I hope you
like it.
> There are 3 methods in the attached class:
> prefix: searches through a string and prefixes a match
> suffix: searches through a string and suffixes a match
> around: does both, prefix or suffix may be null.
