问题描述
为了实现互操作性，我需要从Java代码传递Scala PartialFunction。对于Function（Function1等），我可以使用匿名类型对AbstractFunction进行子类化，但对PartialFunction执行相同操作的最简单方法是什么？
For interoperability, I need to pass a Scala PartialFunction from Java code. For Function (Function1 and so on), there is AbstractFunction that I can subclass with an anonymous type, but what would be the easiest way of doing the same for PartialFunction?
在这种情况下，我很乐意将它作为Java中的完整函数，出现为所有值定义，但键入为PartialFunction。
In this case, I would be happy to have it being a "complete" function in Java, appearing defined for all values, but typed as a PartialFunction.
推荐答案
如果您可以使用Twitter Util库，它有一个专门用于此类的类：与AbstractPartialFunction基本相同。
If you can use Twitter Util library, it has a class specifically for this: http://twitter.github.com/util/util-core/target/site/doc/main/api/com/twitter/util/Function.html which is basically the same solution as AbstractPartialFunction.
