Subject [jira] [Commented] (LANG-1345) Add methods to enhance non-empty strings
Date Wed, 06 Sep 2017 22:48:00 GMT

    [ https://issues.apache.org/jira/browse/LANG-1345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16156153#comment-16156153
] 

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.

> 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.
