Unfortunately, I am not aware of any comprehensive documentation for the internal Java implementation of Clojure's core data types. The source code is the only definitive resource.
Introspection can help. For example, to get a list of everything you need to implement to support map-like behavior: user=> (ancestors (class {})) #{clojure.lang.IObj clojure.lang.Seqable clojure.lang.IHashEq clojure.lang.IMeta java.util.concurrent.Callable clojure.lang.IFn java.io.Serializable clojure.lang.IEditableCollection clojure.lang.APersistentMap clojure.lang.Associative java.util.Map clojure.lang.IPersistentCollection java.lang.Object clojure.lang.AFn java.lang.Runnable clojure.lang.Counted clojure.lang.MapEquivalence java.lang.Iterable clojure.lang.IPersistentMap clojure.lang.ILookup} -S -- You received this message because you are subscribed to the Google Groups "Clojure" group.
