Classes can be developed +in an extension language, such as C or C++, and these classes can be +treated like other python classes. They can be sub-classed in python, +they provide access to method documentation strings, and they can be +used to directly create new instances. + +Extension classes provide additional extensions to class and instance +semantics, including A protocol for accessing subobjects "in the context +of" their containers. This is used to implement custom method types and +environmental acquisition*. A protocol for overriding method call +semantics. This is used to implement "synchonized" classes and could be +used to implement argument type checking. A protocol for class +initialization that supports execution of a special __class_init__ +method after a class has been initialized. + +(* see http://www.digicool.com/releases/ExtensionClass/Acquisition.html) |
