7.7.3 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 Object Creation and Initialization.

Notes::

The consequences of adding methods to allocate-instance is unspecified. This capability might be added by the Metaobject Protocol.
