public class Child
extends Opcode

Child expects a clause of the form (:CHILD parent child). If the form is ground the child must be a child of the parent (i.e. parent is a class and child is a direct or indirect subclass or instance of that class). If the clause is not ground, this command retrieves all subclasses and instances of the class. User: hewett Date: Jan 09, 2003 Time: 2:05:44 PM
