我明白等同于Scala中的 flatMap 是 mapcat 。
I understand the equivalent to flatMap in Scala is mapcat in Clojure.
在clojure中, mapcat 只适用于序列,不像 flatMap 在Scala中更灵活。
I have an inkling that mapcat in clojure only works with sequences, unlike flatMap in Scala which is more flexible.
我的问题是 - 在Clojure中的 mapcat 和 flatMap 在Scala中他们的操作方面?
My question is - what are the differences between mapcat in Clojure and flatMap in Scala in terms of what they operate on?
假设:
- 我理解Scala有一个丰富的类型系统和Clojure有可选的打字 - 我有兴趣知道是否是mapcat接受的参数的限制,使它只有 flatMap 的功能的一个子集。
- I understand that Scala has a rich type system and Clojure has optional typing - I'm interested to know if the is a limitation in the parameters that mapcat accepts that make it only have a subset of flatMaps functionality.
在标准Scala库中: 响应者 , 未来 , 解析器 , ControlContext 。它们都不是序列或特别是序列样。 中还有一些细微变化 ParseResult 。
In the standard Scala library: Responder, Future, Parser, ControlContext. None of them are sequences or particularly sequence-like. There is also a slight variation in ParseResult.
