reinitialize-instance [Standard Generic Function]

Syntax::

reinitialize-instance instance {&rest initargs {&key} {&allow-other-keys}} => instance

Method Signatures::

reinitialize-instance (instance standard-object) {&rest initargs}

Arguments and Values::

instance---an object.

initargs---an initialization argument list.

Description::

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.

Side Effects::

The generic function reinitialize-instance changes the values of local slots.

Exceptional Situations::

The system-supplied primary method for reinitialize-instance signals an error if an initarg is supplied that is not declared as valid.

Notes::

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.
