When an Apple event reaches a Cocoa application, Cocoa’s built-in scripting support transforms it into a script command (that is, an instance of
NSScript or one of the subclasses provided by Cocoa scripting or by your application) and executes the command in the context of the application. Executing a command means either invoking the selector associated with the command on the object or objects designated to receive the command, or having the command perform its default implementation method (
Your application most likely calls methods of
NSScript to extract the command arguments. You do this either in the
perform method of a command subclass you have created, or in an object method designated as the selector to handle a particular command.
As part of Cocoa’s standard scripting implementation,
NSScript and its subclasses can handle the default command set for AppleScript's Standard suite for most applications without any subclassing. The Standard suite includes commands such as
move, as well as common object classes such as
