Utilities that make CLOS behave more like traditional OOP.
========
(DEFPROTOCOL (&optional common-args) (generic-fn-name generic-fn-args &optional docstring*) ...)
common-args -- Arguments common to each generic function in the protocol. These will be the first arguments, and the arguments specified elsewhere will be appended to them.
generic-fn-name -- Name of the generic function generic-fn-args -- Arguments specific to that generic function, appended to the end of common-args. docstring -- Optional docstring
Example:
(defprotocol (my-arg your-arg)
(f1 (arg1) "Example function 1")
(f2 (arg2 &key key1 key2)))
=>
(defgeneric f1 (my-arg your-arg arg1)
(:documentation "Example function 1"))
(defgeneric f2 (my-arg your-arg arg2 &key key1 key2))========
DEFMETHOD* behaves exactly like DEFMETHOD, but if one its arguments are named SELF it allows for easy access to slots and accessors with the sigils $ and @ respecitively.
Example:
(defclass foo ()
(x)
(y :accessor y))
(defmethod* add ((self foo) (num number))
(+ $x @y num))
=>
(defmethod add ((self foo) (num number))
(+ (slot-value self 'x) (y self) num))
