Arguments and Values


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 \secref\ObjectCreationAndInit.
