OK, I wrote Optionals for JDK8 which adds static functions map, flatMap, and toIterable
http://pastebin.com/HZ1suSRt (I would probably adjust the generics type boundaries if this was a serious effort) So that these work: map(optObj, (o) -> ...); flatMap(optObj, (o) -> ...); for (T t : toIterable(optObj)) { ... } For at least the first two, C#-style extension methods would offer more natural syntax, but I don't think that is a big deal: optObj.map((o) -> ...); optObj.flatMap((o) -> ...); The major downside is that this will be another third-party add-on library and not built-in to the core standard library. Will third party libraries -- mainly Functional Java but also others like Atlassian Fugue -- standardize on the JDK8 option and use static methods for the omitted features or will they continue to use completely separate Option class implementations? -- You received this message because you are subscribed to the Google Groups "Java Posse" group.
