allocate-instance
allocate-instance Standard Generic Function
Syntax:
allocate-instance class &rest initargs &key &allow-other-keys → new-instance
Method Signatures:
allocate-instance (class standard-class) &rest initargs
allocate-instance (class structure-class) &rest initargs
Arguments and Values:
class—a class.
initargs—a list of keyword/value pairs (initialization argument names and values). new-instance—an object whose class is class.
Description:
The generic function allocate-instance creates and returns a new instance of the class, without initializing it. When the class is a standard class, this means that the slots are unbound; when the class is a structure class, this means the slots’ values are unspecified.
The caller of allocate-instance is expected to have already checked the initialization arguments.
The generic function allocate-instance is called by make-instance, as described in Section 7.1 (Object Creation and Initialization).
