When defining a class and specifying allowable subclasses (AllowedSubclasses = ?ClassName), can I specify a package instead? For example:

 classdef SuperClass (AllowedSubclasses = ?PackageName)
   ...
or
 classdef SuperClass (AllowedSubclasses = ?PackageName.*)
   ...

Thanks!

Hello Sean,

I understand that you want to use “AllowedSubclasses” function but with package names.

However, there isn’t a way of specifying that in MATLAB because the “AllowedSubclasses” parameter accepts only fully qualified class name while referencing a class name.

You can specify multiple classes in the “classdef” of your super class using the “AllowedSubclasses” parameter using a cell array of meta.class objects to define more than one allowed subclass:

classdef (AllowedSubclasses = {?ClassName1,?ClassName2,...?ClassNameN}) MySuperClass ... end

Please refer to the below link for more details on the same:

Hope this helps!
