Subject [jira] Created: (LANG-358) ObjectUtils.coalesce
Date Fri, 12 Oct 2007 06:27:51 GMT
ObjectUtils.coalesce
--------------------

                 Key: LANG-358
                 URL: https://issues.apache.org/jira/browse/LANG-358
             Project: Commons Lang
          Issue Type: New Feature
    Affects Versions: LangTwo 1.0
            Reporter: Jörg Gottschling
            Priority: Minor


I like to see the coalesce-function from SQL implemented in ObjectUtils. Something like this:
<T> T ObjectUtils.coalesce(T... t)
The first object, which is not null will be returned. I think it's simple. Perhaps there should
be overloading methods with fixed parameter sizes. Following the jdk this seems to a little
faster:
<T> T ObjectUtils.coalesce(T t1, T t2)
<T> T ObjectUtils.coalesce(T t1, T t2, T t3)
...

I would provide it, including tests, if you like.
