ensure-class

Function ENSURE-CLASS

Syntax:

ensure-class name &key &allow-other-keys => class

Arguments and values:

name -- A symbol.

class -- A class metaobject.

Description:

Some of the keyword arguments accepted by this function are actually processed byensure-class-using-class, others are processed during initialization of the class metaobject (as described in the section called ``Initialization of Class Metaobjects'').

This function is called to define or redefine a class with the specified name, and can be called by the user or the implementation. It is the functional equivalent of defclass, and is called by the expansion of the defclass macro.

The behavior of this function is actually implemented by the generic function ensure-class-using-class. When ensure-class is called, it immediately calls ensure-class-using-class and returns that result as its own.
