“With” statement equivalent for Scala?

Question

Idle pondering from a Scala learner perhaps, but ... in my tinkerings I\'ve written the following:

( n.child.size > 0 ) && ( n.child.filter( ! _.isIns         


        

Answer 1

you can use match for that purpose.

n.child match {
case list => ( list.size > 0 ) && ( list.filter( ! _.isInstanceOf[Text] ).size == 0 )
}
