| 7.7.4 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.

Section 7.1.4 Rules for Initialization Arguments,
Section 7.1.2 Declaring the Validity of Initialization Arguments
- 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.
