Editing Method (computer programming) (section)

==Class methods==
Class methods are methods that are called on a [[Class (computer programming)|class]] rather than an instance. They are typically used as part of an object [[meta-model]]. I.e, for each class, defined an instance of the class object in the meta-model is created.  [[Meta-object protocol|Meta-model protocols]] allow classes to be created and deleted. In this sense, they provide the same functionality as constructors and destructors described above. But in some languages such as the [[Common Lisp Object System|Common Lisp Object System (CLOS)]] the meta-model allows the developer to dynamically alter the [[object model]] at run time: e.g., to create new classes, redefine the class hierarchy, modify properties, etc.
