FLI question

Hello,

is it possible to specify somehow the initial contents for a FLI structure as 
in the example :

(fli:define-c-struct POS
  (x :int)
  (y :int)
  (z :int))

(setq my-pos (fli:allocate-foreign-object :type 'POS :inital-contents ?????))

Thanks and with best regards

Question about FLI:WITH-DYNAMIC-FOREIGN-OBJECTS


Hello,

If I have the following definitions :

(fli:define-c-struct (mt-timestamp (:foreign-name "xxx"))
                     (year mt-short)
                     (month mt-short)
                     (day mt-short)
                     (hour mt-short)
                     (minute mt-short)
                     (second mt-short)
                     (microsecs mt-integer))
(fli:define-c-typedef (mt-timestamp (:foreign-name "xxx"))
                      (:struct mt-timestamp))

(defclass mh-timestamp ()
  ((fs :initform (let ((fs (fli:allocate-dynamic-foreign-object :type 'mt-
timestamp)))
                   (setf (fli:foreign-slot-value fs 'microsecs) 0)
                   (setf (fli:foreign-slot-value fs 'second) 0)
                   (setf (fli:foreign-slot-value fs 'minute) 0)

                   (setf (fli:foreign-slot-value fs 'day) 1)

KW objects


Hi all,

I've been working with kw-objects and I've got a little problem. I have 
an object of a given class that contains some instance variables with 
list with other objects (these are the kw-objects). The idea is to send 
only 1 object to file for "saving an image" of my program. When I load 
this "image" I can see the first object and inspect its instance 
variables to look at the other objects. Nevertheless, when I query for 
objects in the kw-listener (or in the objects inspector) I get no 
result. I mean, the objects exist (because I can see them by inspecting 
the "root" object I've saved) but I cannot see them when querying with 
kw! anyone has an idea of what's happening?

thanks,
Miro Casanova

You have to explain how you save and load your objects. KW's internal
RETE network needs to be told about KW objects. Usually it notices
them by watching MAKE-INSTANCE (I think) so maybe you are loading them
in some other way?

Re: KW objects


Hi,

This is the code (summarized).

(defclass library-container ()
   ((struct-root :accessor struct-root :initform '()))

the struct-root:

(kw:def-kb-class structure-root ()
   ((dimensions :accessor dimensions :initform '())))

the dimension objects:

(kw:def-kb-class dimension ()
   ((name :accessor name :initform "")
    (facets :accessor facets :initform '())))

and the facets objects:

(kw:def-kb-class facet ()
   ((name :accessor name :initform ""))

This is the way I save the image:
->first, I have a global variable:

(defparameter *library-pool-instance* (make-instance 'library-container))

->second, I save like this:

Hi,
I do have make-load-form methods

(defmethod make-load-form ((self dimension) &optional environment)
   (make-load-form-saving-slots self))

(also for facet, structure-root, and library-container, always with the 
same body).
I expected that by loading the objects they would be also put in the KW 
"memory".

Try taking them out and see if KW has any that DTRT.

Re: KW objects


I tried this:

(defmethod make-load-form ((self dimension) &optional environment)
   (values
     `(make-instance ',(class-of self))
     `(progn
        (setf (name ',self) ',(slot-value self 'name))
        (setf (facets ',self) ',(slot-value self 'facets))
        (setf (docs ',self) ',(slot-value self 'docs))
        (setf (basic-clusters ',self) ',(slot-value self 'basic-clusters))
        (setf (root ',self) ',(slot-value self 'root)))))

instead of the :  (make-load-form-saving-slots self)

and it works! which it is quite strange....
I expected the make-load-form-saving-slots to do the same!
