Hi,
I'm trying to extend the inputParser class, and hereby also extend the method parse() from that class.
Is it at all possible? The documentation seems to explain how to do this:
https://se.mathworks.com/help/matlab/matlab_oop/modifying-superclass-methods-and-properties.html
Here is my subclass with extended method:
classdef myInputParser < inputParser
properties
Extra
end
methods
% Class constructor
function obj = myInputParser()
obj.Extra.test = 0;
end
% Extend inputParser superclass method parse()
function parse(obj, varargin)
% preprocessing steps
parse@inputParser(obj, varargin{:});
% postprocessing steps
obj.Extra = obj.Results;
end
end
end
I create the object, and parse the input like so:
p = myInputParser;
p.parse(varargin{:})
When calling the parse() method on the object, it doesn't seem to call the extended parse() in the subclass.
What am I missing? Any help would be greatly appreciated.

When I restarted MATLAB, it worked.
After that I read about the command "clear classes", which might have helped as well. I had to clear the cache or something.

Yes, but the name of the constructor should be identical to the name of the class.
And the method
function parse(obj)
% preprocessing steps
parse@inputParser(obj);
% postprocessing steps
obj.Extra = obj.Results;
end
should read something like
function parse(obj,varargin)
% preprocessing steps
parse@inputParser(obj,varargin{:});
% postprocessing steps
obj.Extra = obj.Results;
end
