1) would be more:
- define a protocol for each kind of function (render, serialize...)
- define a deftype/defrecord for each type of element, and make them extend
the protocol
It's not that different from 2. (protocol, as far as I understand, are
multimethod whose dispatch function is the type of first arg)
More choice:
3)
(defn render "rendering"
[obj context]
(case (:shape obj)
:line (render-line obj context)
.....
)
with obj being a PersistentHashMap {:shape :line :begin {:x :y} ...}
The right choice depends somehow of taste.
I would do for 1, but other would do differently I think.
Good thing with a multi-paradigm language.
