ANSI Common Lisp 7 Objects 7.7 Dictionary of Objects

7.7.36 initialize-instance Standard Generic Function

Syntax:

initialize-instance instance &rest initargs &key &allow-other-keys instance

Method Signatures:

initialize-instance (instance standard-object) &rest initargs

Arguments and Values:

instance - an object.

initargs - a defaulted initialization argument list.

Description:

Called by make-instance to initialize a newly created instance. The generic function is called with the new instance and the defaulted initialization argument list.

The system-supplied primary method on initialize-instance initializes the slots of the instance with values according to the initargs and the :initform forms of the slots. It does this by calling the generic function shared-initialize with the following arguments: the instance, t (this indicates that all slots for which no initialization arguments are provided should be initialized according to their :initform forms), and the initargs.

Programmers can define methods for initialize-instance to specify actions to be taken when an instance is initialized. If only after methods are defined, they will be run after the system-supplied primary method for initialization and therefore will not interfere with the default behavior of initialize-instance.

Allegro CL Implementation Details:

None.
