Thanks for the big help, I treated the protocol as interface. :)
no worries :)
I was also surprised to see that you are type-hinting the
clojure.lang.Atom...why would you do that? from what I can see you are
only using `reset!` and `swap!`...I doubt that you are getting
reflection with these...
Jim
also sorry for nitpicking but I saw this:
(map [this f]
(let [^DBIterator iterator (.iterator db)]
(.seekToFirst iterator)
(while (.hasNext iterator)
(let [^Map$Entry kv (.peekNext iterator)
k (.getKey kv)
v (.getValue kv)]
(f k v)
(.next iterator)))))
did you know that clojure has a built-in function `iterator-seq` ? While
I don't know much about levelDB, I suspect you can make this a lot nicer
and simpler like so:
(map [this f]
(let [^DBIterator iterator (.iterator db)]
(.seekToFirst iterator)
(clojure.core/map #(apply f %) (iterator-seq iterator))))
