Sebb commented on LANG-1345:
----------------------------
Sorry, but I think this is straying far beyond the remit of the LANG library.
It's probably also not appropriate for the TEXT library.
IMO this sort of code belongs in the application.
> Add methods to enhance non-empty strings

> Key: LANG-1345
> URL: https://issues.apache.org/jira/browse/LANG-1345
> Project: Commons Lang
> Issue Type: Improvement
> Components: lang.*
> Reporter: Mitth'raw'nuruodo
> Priority: Minor
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> As a corollary to {{defaultString}}, {{appendIfMissing}}, and similar
> methods, which allow the client to replace a missing string with something,
> it would sometimes be helpful to have methods that enhance a string, if it is
> present, with a prefix and suffix (or perhaps with an arbitrary function).
> Eg
> {code}
> if (StringUtils.isNotEmpty(queryString)) {
> return url + "?" + queryString;
> } else {
> return url;
> }
> {code}
> would become:
> {code}
> return url + StringUtils.addIfNotEmpty(queryString, "?", null);
> {code}
> with the second parameter being the prefix, and the third, the suffix. If the
> string is null or empty, return empty string.
> If this could accept arbitrary transformation functions, it could effectively
> become the Elvis operator.
