i have the following class
(defclass vgdb () ((name :initarg name :accessor name)
(modes :initarg modes :accessor modes)
(h :accessor h)))
and the following initialize-instance
(defmethod initialize-instance :after ((v vgdb) &rest i)
(with-open-file (in (name v) :direction (modes v)) (setf (h v) (read in))))
when i execute these expressions i get the warning
The generic function #<GENERIC-FUNCTION INITIALIZE-INSTANCE> is being modified, but has already been called.
#<STANDARD-METHOD :AFTER (#<STANDARD-CLASS VGDB>)>
what i am trying to do is to load a hash table after name gets set with the
contents of the file referred to by name.
my question: is this the proper use of initialize-instance or is there
a more correct way of doing this. also where did initialize instance
get called for this class.
