how can one avoid boxing when using function
Thu, 2011-09-22, 08:13
Hi, I am trying to figure out how to avoid boxing because the performance hit is killing me. As an experiment I wrote the following code:
object X { def main(args:Array[String]) { val b = new B[Int](3) while(true) { b.foreach(_ + 1) } }}
class B[@specialized(Int)A](val a:A) { def foreach(f: A => Unit) = f(a) }
Sadly, when I look at the byte code the foreach method is still boxing. In my actual application I am writing a custom collection that always contains ints and I need to get around the boxing. Any suggestions?
