Re: [lang] StringUtils.substringAfter()

[__matthewHawthorne]

I don't think that your case is unusual.  Actually, I would expect 
stripStart to do what you want, and (a nonexistent) stripStart(String, 
char[]) to do what the current stripStart(String, String) does.

However, this doesn't solve your problem.  I think your suggestion would 
be useful, but I'm not sure about a name either.

Subject: [lang] StringUtils.substringAfter()
Hello,

I find the current behavior of StringUtils.substringAfter() not quite
right
for my needs. For example, I want to strip the leading 'www.' in a host
string. If the search string is not there, the empty string is returned,
which force me to write:
String host = ...
String strippedHost = StringUtils.substringAfter(host, "www.");
if (StringUtils.isEmpty(strippedHost)) {
  strippedHost = host;
}
//continue with stripped host.
Instead of:

String host = ...
String host = StringUtils.substringAfter(host, "www.");
//continue with stripped host.
If the API returned the its argument instead of "".

You'd think stripStart would do this but stripStart works on a character
set, not a string prefix.
So:

(1) I do not thing that changing the current API is nice.

(2) Does this case warrant a new API? Or is this case really unusual?
New API: stripStartString(String, String)
Perhaps rename (deprecate etc) startStart to startStartCharSet?
Thanks,
Gary
