If you look up a couple of lines on that same page, you'll see that
paragraph put into context:

The key to messaging lies in the structures that the compiler builds
for each class and object. Every class structure includes these two
essential elements:
■A pointer to the superclass.
■A class dispatch table. This table has entries that associate method
selectors with the class-specific addresses of the methods they
identify. The selector for the setOrigin:: method is associated with
the address of (the procedure that implements) setOrigin::, the
selector for the display method is associated with display’s address,
and so on.
---------
So, every class has it's own class dispatch table.
right, i see. thanks.
