Traversable => Java Iterator
- by Andres
I have a Traversable, and I want to make it into a Java Iterator. My problem is that I want everything to be lazily done. If I do .toIterator on the traversable, it eagerly produces the result, copies it into a List, and returns an iterator over the List.
I'm sure I'm missing something simple here...
Here is a small test case that shows what I mean:
class Test extends Traversable[String] {
def foreach[U](f : (String) => U) {
f("1")
f("2")
f("3")
throw new RuntimeException("Not lazy!")
}
}
val a = new Test
val iter = a.toIterator
