早jdk8-ea javadocs like this表示有一个 java.util.stream.Streamable接口(interface)，这似乎与 Stream 具有相同的关系作为Iterable有一个Iterator .
现在我们似乎陷入了 Supplier<Stream> 的困境，这当然不一样。
Streamable 发生了什么？
最佳答案
它已经被删除了一段时间。 The rationale删除由 Brian Goetz 给出:
Currently the only implementor is Collection, and all of the other stream-bearing methods are serving up specialized streams (chars(), codePoints(), lines(), etc) with a method name that is more suitable than "stream". So I think we should drop Streamable and leave the stream() / parallel() methods on Collection (or possibly move them up Iterable).
And also :
I'm starting to think that Streamable is not carrying its weight. I'd like to consider dropping Streamable, at which point the base-most implementation of parallel() is in Collection, and I'd also suggest we consider renaming that to parallelStream().
在this other post他补充道:
if everything that is Iterable is effectively Streamable (because Iterable has a stream()) method, and everything Streamable is effectively Iterable (because you can turn a Spliterator into an Iterator), aren't they then the same abstraction?
