Java <->Scala 集合转换，Scala 2.10 [英] Java <-> Scala Collection conversions, Scala 2.10

问题描述

查看 JavaConversions 和 JavaConverters 中的代码，我不确定哪种正确"方式(使用 2.10)在 Java 和 Scala 集合之间转换(在任一方向)) 是.

Looking at the code in JavaConversions and JavaConverters, I am unsure which the "correct" way (with 2.10) to convert between Java and Scala collections (in either direction) is.

似乎有很多@deprecated 注释.

There seem to be lots of @deprecated annotations.

Scala 团队(类型安全?)是否发布了明确的答案?

Has a definitive answer from the Scala Team (Typesafe?) been published?

谢谢，约翰

推荐答案

我不知道有任何此类声明，但您应该始终使用 JavaConverters，即需要您指出的那些使用 .asScala 和 .asJava 进行转换.

I don't know of any such proclamation, but you should just always use JavaConverters, i.e. the ones that require you to indicate conversions with .asScala and .asJava.

据我所知，JavaConverters 是在 2.8.1 中引入的，因为 2.8 中的 JavaConversions 很危险，并且很容易意外地转换你没有的东西期待.

As I understand it, JavaConverters were brought in in 2.8.1 because the JavaConversions in 2.8 were dangerous and made it easy to accidentally convert things where you weren't expecting it.
