I've not worked with protocols much, but saw a good fit recently. However, I'm a little bit unsure about this situation. I have some Thrift objects that I'd like to be able to easily unpack into maps, so I created a protocol
(defprotocol Unpackable (unpack [x])) Thrift has two main data types - structs and unions that need to be handled differently. Structs always implement the interface TBase. Unions extend the abstract class TUnion which in turn implements the interface TBase. So I'm extending my protocol to these types like this: (extend-protocol IUnpackable TUnion (unpack [x] (unpack-union x)) TBase (unpack [x] (unpack-struct x (get-meta-data (class x))))) It all seems to work correctly, but I'm a little unsure that it is guaranteed to work especially in the case of a union. Since a union extends TUnion, but also implements TBase will a call to (unpack the-union) do the right thing (go to unpack-union instead of unpack-struct) every time?
