  • best scala idiom for find & return

    - by IttayD
    This is something I encounter frequently, but I don't know the elegant way of doing. I have a collection of Foo objects. Foo has a method bar() that may return null or a Bar object. I want to scan the collection, calling each object's bar() method and stop on the first one returning an actual reference and return that reference from the scan.

I've seen all sorts of bits all over the internet where verbatim LIKE SQL clauses are used - but from what I've heard that isn't the 'correct' way of doing it. Is there a 'proper' Rails way?
