(multi-add multi dispatch-val method)

adds an entry to the multimethod

(multi-add world :c (fn [m] (assoc m :c 3))) => world

multi-clone clj

(multi-clone source name)

creates a multimethod from an existing one

(defmulti hello :type)

(defmethod hello :a [m] (assoc m :a 1))

(def world (multi-clone hello "world"))

(defmethod world :b [m] (assoc m :b 2))

(world {:type :b}) => {:type :b :b 2}

;; original method should not be changed (hello {:type :b}) => (throws)

multi-get clj

(multi-get multi dispatch)

returns all entries in the multimethod

(multi-get world :b) => fn?

multi-has? clj

(multi-has? multi val)

returns true if the multimethod contains a value for dispatch

(multi-has? print-method Class) => true

multi-keys clj

(multi-keys multi)

returns all keys for a given multimethod

(multi-keys world) => #{:a :b}

multi-list clj

(multi-list multi)

returns all entries in the multimethod

(multi-list world) => (satisfies [:a :b] (comp vec sort keys))

multi-match? clj

(multi-match? multi method)

(multi-match? multi method throw?)

checks if the multi dispatch matches the arguments

(multi-match? (.dispatchFn string/-from-string) (fn [_ _ _])) => true

(multi-match? (.dispatchFn string/-from-string) (fn [_]) true) => (throws)

multi-remove clj

(multi-remove multi dispatch)

removes an entry

(multi-remove world :b) => fn?

multi? clj

(multi? obj)

returns true if obj is a multimethod

(multi? print-method) => true

(multi? println) => false
