Maximum Length for scala queue

Question

I\'m curious if Scala has some gem hidden in its collection classes that I can use. Basically I\'m looking for something like a FIFO queue, but that has an upper-limit on i

Answer 1

Why don't you just subclass a FIFO queue? Something like this should work: (pseudocode follows...)

class Limited(limit:Int) extends FIFO {
  override def enqueue() = {
    if (size >= limit) {
      //remove oldest element
    }
    super.enqueue()
  }
}
