checks whether a type has implemented a protocol

(class:implements? state/IStateGet clojure.lang.Atom) => true

returns types that implement the protocol

(protocol:impls state/IStateSet) => (any (contains clojure.lang.Agent clojure.lang.Ref clojure.lang.IAtom clojure.lang.Volatile clojure.lang.IPending clojure.lang.Var :in-any-order :gaps-ok) #{})

(protocol:impls state/IStateGet) => (any (contains clojure.lang.IDeref clojure.lang.IPending :in-any-order :gaps-ok) #{})

returns the java interface for a given protocol

(protocol:interface state/IStateGet) => std.protocol.state.IStateGet

returns the methods provided by the protocol

(protocol:methods state/IStateSet) => ’-clone-state -empty-state -set-state -update-state

removes a protocol

(defprotocol -A- (-dostuff _))

(do (extend-protocol -A- String (-dostuff _))

(class:implements? -A- String "-dostuff"))

=> true

(do (protocol:remove -A- String) (class:implements? -A- String “-dostuff”)) => false

returns the method signatures provided by the protocol

(protocol:signatures state/IStateSet) => ’{-update-state {:arglists (obj f args opts) :doc nil} -set-state {:arglists (obj v opts) :doc nil} -empty-state {:arglists (obj opts) :doc nil} -clone-state {:arglists (obj opts) :doc nil}}

checks whether an object is a protocol

(protocol? state/IStateGet) => true
