关于评估2D流的OutOfMemoryError

Question

为什么以下导致OutOfMemoryError？

scala> Stream.tabulate(3, 4)(_ + _)
res0: scala.collection.immutable.Stream[scala.collection.immutable.Stream[Int]] = Stream(Stream(0, ?), ?)

scala> res0.length

应用size和force方法也是如此.

Answer 1

2.8中有一个错误:"Stream.tabulate创建一个无限的流"

看一看. http://lampsvn.epfl.ch/trac/scala/ticket/3508
