Return a list containing the direct subclasses of class. This is the value of class’s direct-subclasses slot.

primitive procedure: class-direct-methods class ¶

Return a list of all the generic function methods that use class as a formal parameter specializer. This is the value of class’s direct-methods slot.

primitive procedure: class-precedence-list class ¶

Return the class precedence list for class class (see Class Precedence List). This is the value of class’s cpl slot.

primitive procedure: class-slots class ¶

Return a list containing the slot definitions for all class’s slots, including any slots that are inherited from superclasses. This is the value of class’s slots slot.

procedure: class-subclasses class ¶
