Standard Generic Function INITIALIZE-INSTANCE

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.

Examples: None.

Affected By: None.

Exceptional Situations: None.
