instance | an object. |
initargs | an initialization argument list. |
The generic function reinitialize-instance can be used to change the values of local slots of an instance according to initargs. This generic function can be called by users.
The system-supplied primary method for reinitialize-instance checks the validity of initargs and signals an error if an initarg is supplied that is not declared as valid. The method then calls the generic function shared-initialize with the following arguments: the instance, nil (which means no slots should be initialized according to their initforms), and the initargs it received.
The generic function reinitialize-instance changes the values of local slots.
The system-supplied primary method for reinitialize-instance signals an error if an initarg is supplied that is not declared as valid.

Initargs are declared as valid by using the
:initarg
option to defclass, or by defining
methods for reinitialize-instance
or shared-initialize. The keyword name
of each keyword parameter specifier in the lambda list of any
method
defined on reinitialize-instance or shared-initialize is
declared as a valid initialization argument name for all
classes for
which that method is applicable.
