writer-method-class (class direct-slot &rest initargs)

The class argument is a class metaobject.
The direct-slot argument is a direct slot definition metaobject.
The initargs argument is a list of initialization arguments and values.

The value returned is a class metaobject.

This generic function is called to determine the class of writer methods created during class initialization and reinitialization. The result must be a subclass of standard-writer-method.

The initargs argument must be the same as will be passed to make-instance to create the reader method. The initargs must include :slot-definition with slot-definition as its value.
