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 Object Creation and Initialization.

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