Re: Space/outrigger suggestions

You are talking about a a field of an Entry, but it does aim at generics type safety. Too, the fields of an Entry as returned per the specification are not to be of different class types than what were given. If the instances contained in the collection given during a write are String...they wi

Re: Space/outrigger suggestions

There is one additional problem, the use of generics causes a narrowing of scope, the template and return value must be the same type. The entry spec currently allows the template to be a different class, a dummy class can be used instead. Once Generics are introduced into service api, at the

In this case, I believe one must first prove the contrary; prove there is a problem with generics in this case. Is there an example of where this proposal for JavaSpaces causes an issue. I don't know of any. I would be very surprised if one could give a working example of such an issue. We are t

Re: Space/outrigger suggestions

There seems to be support for using generics in this case. If we can develop some good documentation to explain why it works and why it's the exception to the rule for using generics in service api, if this is indeed the case, then I think it is acceptable. Do we have any good wordsmith's on th

I don't know. Checks etc in this case, before calling read on the return or parameter type, just doesn't make any sense to me. If Jini returns an incorrect instance then it is simply in error per the specification. If you pass in a template, you expect to have that exact type, possibly an extens

Re: Space/outrigger suggestions

I think we're approaching a common understanding. I'm familiar with type erasure, and am aware that my proposed method signature erases down to the current method signature. When I spoke of the additional specification power and type safety, I wasn't speaking at the byte-code level, but at the

Re: Space/outrigger suggestions

I think the difference between generics vs not-generics in this case is to do with expectations. If generics are used on the method signature then the client developer *expects* not to encounter any runtime issues. In certain circumstances this expectation is incorrect. The method signature with
