overwrite Handle class - hide 'isvalid' function and 'ObjectBeingDestroyed' event

Dear all,

I want to make a class that is to be used by people that are very unfamiliar with Matlab and they will be using the class by consulting doc('myClass'). The class is based on the handle class, the problem is that the functions inherited from the handle class are also displayed in the documentation. Some of these inherited functions can be hidden by overwritting them as follows (link to original post):

classdef myClass < handle
    methods (Hidden)
        function lh = addlistener(varargin)
         lh = addlistener@handle(varargin{:});
        end
        function notify(varargin)
         notify@handle(varargin{:});
        end
        function delete(varargin)
         delete@handle(varargin{:});
        end
        function Hmatch = findobj(varargin)
         Hmatch = findobj@handle(varargin{:});
        end
        function p = findprop(varargin)
         p = findprop@handle(varargin{:});
        end
        function TF = eq(varargin)
         TF = eq@handle(varargin{:});
        end
        function TF = ne(varargin)
         TF = ne@handle(varargin{:});
        end
        function TF = lt(varargin)
         TF = lt@handle(varargin{:});
        end
        function TF = le(varargin)
         TF = le@handle(varargin{:});
        end
        function TF = gt(varargin)
         TF = gt@handle(varargin{:});
        end
        function TF = ge(varargin)
         TF = ge@handle(varargin{:});
        end
    end
end

However, the 'isvalid' function is 'sealed' and cannot be overwritten to hide it. The event 'ObjectBeingDestroyed' can also not be overwritten to hide it.

My question is therefore, is it possible to copy the source code of the original handle class into a new custom class which can then be altered to hide all the functions and events? Or is there some other way to hide this function and event?

Kind regards,

Dennis

is it possible to copy the source code of the original handle class

No, we don't have access to that source code. In any case it's a fundamental base clase compiled into matlab executable, I doubt you'd be able to reproduce its behaviour purely in m code.

At this point, I think you need to bite the bullet and write your own custom documentation rather than relying on the autogenerated one.

I was afraid of that. Thanks for your quick answer!
