MATLAB Object-Oriented Programming

• Define their own method with the same name (if not a subclass).


• Override the method in a subclass only if the superclass defining the method includes
  itself or the subclass in the access list.

These sample classes show the behavior of methods called from methods of other classes

that are in the access list. The class AcListSuper gives the AcListNonSub class access

to its m1 method:

classdef AcListSuper

methods (Access = {?AcListNonSub})

function obj = m1(obj)

disp ('Method m1 called')

end

end

end

Because AcListNonSub is in the access list of m1, its methods can call m1 using an

instance of AcListSuper:

classdef AcListNonSub

methods

function obj = nonSub1(obj,AcListSuper_Obj)

% Call m1 on AcListSuper class

AcListSuper_Obj.m1;

end

function obj = m1(obj)

% Define a method named m1

disp(['Method m1 defined by ',class(obj)])

end

end

end

Create objects of both classes:

a = AcListSuper;

b = AcListNonSub;

Call the AcListSuper m1 method using an AcListNonSub method:

b.nonSub1(a);

Method m1 called

Call the AcListNonSub m1 method:
