Jörg Gottschling updated LANG-358:
----------------------------------
Attachment: ObjectUtils.java
trivial implementation of coalesce
> ObjectUtils.coalesce
> --------------------
>
> Key: LANG-358
> URL: https://issues.apache.org/jira/browse/LANG-358
> Project: Commons Lang
> Issue Type: New Feature
> Reporter: Jörg Gottschling
> Priority: Minor
> Fix For: LangTwo 1.0
>
> Attachments: ObjectUtils.java
>
>
> 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. This would replace all
> the defaultValue/defaultString/... methods, with al flexibler and shorter
> method. It will also reuse an existing name.
> 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.
