Wrapping null-returning method in Java with Option in Scala?

Suppose I have a method session.get(str: String): String but you don't know whether it will return you a string or a null, because it comes from Java.

Is there an easier way to treat this in Scala instead of session.get("foo") == null ? Maybe some magic apply like ToOption(session.get("foo")) and then I can treat it in Scala way like

ToOption(session.get("foo")) match {
    case Some(_) =>;
    case None =>;
}
