How to check for null in a single statement in scala?

Question

In my scala code:

QueueManager.add(getObject)

where getObject is a method that returns an object of type QueueObject

Answer 1

If it instead returned Option[QueueObject] you could use a construct like getObject.foreach { QueueManager.add }. You can wrap it right inline with Option(getObject).foreach ... because Option[QueueObject](null) is None.
