Concise way in Scala to combine filterNot/match/case

Question

I need to filter a sequence to remove an element that matches a certain case.

This seems too clumsy:

val filtered = 
   headers.filterNot{ case Authorization(_) => true; case _ => false }

Is there a more concise/idiomatic way?

Answer 1

You can use isInstanceOf, like this

headers.filterNot(_.isInstanceOf[Authorization])
