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?
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.
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.
