Subject [jira] [Updated] (LANG-1345) Add methods to enhance non-empty strings
Date Tue, 11 Jul 2017 05:46:00 GMT

     [ https://issues.apache.org/jira/browse/LANG-1345?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mitth'raw'nuruodo updated LANG-1345:
------------------------------------
    Description: 
As a corollary to {{defaultString}} 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.
