class-instance_variables

class <- instance_variables: vector

Vector object holding all instance variables of this class. Initially a copy of the super-class. The variable object at index <n> of this vector describes the <n>-th slot of the object. See also object<-slot.

The behaviour<-context argument may be used to find the class on which a variable is defined. The following code returns a chain of instance variables not inherited:

new(Vs, chain),
send(Class?instance_variables, for_all,
         if(@arg1?context == Class,
                message(Vs, append, @arg1)))
