Last active February 20, 2020 06:15
Transforming java proto instances in clojure maps
;; The main function is `protobuf->map`, which performs the transformation.
;; Runtime reflection can be avoided if class is known beforehand.
;; The macro is completely optional, though it makes things *slightly* easier to read:
;; (protobuf->clj instance OuterClass$InnerClass) vs (protobuf->map instance (OuterClass$InnerClass/getDescriptor))
(defn- *proto->fields
"Get fields from protobuf object's descriptor as clojure keywords"
[descr]
(map #(keyword (.getName %))
(.getFields descr)))
