Sets the object specifier to
receivers that, when evaluated, indicates the receiver or receivers of the command.

If you create a subclass of
NSScript, you don’t necessarily need to override this method, though some of Cocoa’s subclasses do. An override should perform the same function as the superclass method, with a critical difference: it causes the container specifier part of the passed-in object specifier to become the receiver specifier of the command, and the key part of the passed-in object specifier to become the key specifier. In an override, for example, if
receivers is a specifier for
the third rectangle of the first document, the receiver specifier is
the first document while the key specifier is
the third rectangle.
