For maximum flexibility I wanted to use a multimethod, defined like this:
(defmulti intent
(fn [& args]
(apply discern args)))
This is how discern is defined:
(defn- discern
([this-users-conversation]
{:pre [(map? this-users-conversation)]}
(:intent this-users-conversation))
([this-users-conversation salesforce-object-name]
{:pre [(map? this-users-conversation)
(string? salesforce-object-name)]}
(:intent this-users-conversation))
([this-users-conversation salesforce-object-name name-of-attribute]
{:pre [(map? this-users-conversation)
(string? salesforce-object-name)
(string? name-of-attribute)]}
(:intent this-users-conversation))
([this-users-conversation salesforce-object-name name-of-attribute
name-of-intent]
{:pre [(map? this-users-conversation)
(string? salesforce-object-name)
(keyword? name-of-attribute)
(string? name-of-intent)]}
name-of-intent))
but then I call the multimethod like this:
(intent this-users-conversation "Opportunity" :Name
"query-salesforce-for-attribute")
and I get:
:class clojure.lang.ArityException,
:message "Wrong number of args (4) passed to: query/fn--65",
Should I give up on this idea, or is there a way to make this work?
