Annotations are added as metadata to functions in a deftype definition.
Something like this (untested):
(deftype MyType []
SomeInterface
(^{EventHandler {}} onPlayerLogin [event] ...))
For some examples of using annotations:
https://github.com/pallet/clojure-maven/blob/develop/mojo/src/main/clojure/clojure/maven/mojo/defmojo.clj#L45
https://github.com/pallet/zi/blob/develop/src/main/clojure/zi/test.clj#L109
I'm afraid it's not very friendly code if you're new to clojure.
