Methods

There have been a few of the messages and methods in XLISP shown to this point (:NEW and :SHOW). The following are the methods built into XLISP:

:ANSWER

The :ANSWER method allows you to define or change methods within a class.

:CLASS

The :CLASS method returns the class of an object.

:ISNEW

The :ISNEW method causes an instance to run its initialization code. When the :ISNEW method is run on a class, it resets the class state. This allows you to re-define instance variables, class variables, etc.

:NEW

The :NEW method allows you to create an instance when the :NEW message is sent to a user-defined class. The :NEW method allows you to create a new class (when the :NEW message is sent to the built-in CLASS).

:SHOW

The :SHOW method displays the instance or class.
