Subject Re: [lang] Pre 2.0 - StringUtils.isEmpty(), isNotEmpty() and stri ngsa with somespaces
Date Fri, 18 Jul 2003 16:49:26 GMT
I think it would be easier to have different extensions or wrappers for 
StringUtils, such as:

NullFriendlyStringUtils or
TrimmedStringUtils

Or, maybe a type of StringUtilsFactory that could take the params you 
suggested and return a corresponding instance.

This situation seems so controversial, with multiple people 
needing/wanting different behaviors, it seems almost impossible for 
StringUtils to satisfy everyone.  It seems better to keep it simple and 
let some extensions do the work, in that way, the possibilities could be 
unlimited.

Thoughts?
