- slot-set! INSTANCE SLOT-NAME VALUEprocedure
- (set! (slot-ref INSTANCE SLOT-NAME) VALUE)setter
Sets the value of the slot SLOT-NAME of the object INSTANCE to VALUE.
Note that a SLOT-NAME is not required to be a symbol, so the following is perfectly valid:
(define hidden-slot (list 'hidden)) (define <myclass> (make <class> 'direct-supers (list <object>) 'direct-slots (list hidden-slot) ) ) (define x1 (make <myclass>) (slot-set! x1 hidden-slot 99)
To exploit this, however, the make call has to be used as above. define-class only supports symbolic slot names.
