jaskell.multi
multicljmacro
(multi name? dispatch-fn & options)Creates a new "anonymous" multimethod with the associated dispatch function. The docstring is optional.
like fn, you can assign a name for this multimethod, it will pass into MultiFn construction function.
Options are key-value pairs and may be one of:
:default
The default dispatch value, defaults to :default
:hierarchy
The value used for hierarchical dispatch (e.g. ::square is-a ::shape)
Hierarchies are type-like relationships that do not depend upon type inheritance. By default Clojure's multimethods dispatch off of a global hierarchy map. However, a hierarchy relationship can be created with the derive function used to augment the root ancestor created with make-hierarchy.
Multimethods expect the value of the hierarchy option to be supplied as a reference type e.g. a var (i.e. via the Var-quote dispatch macro #' or the var special form).
