dynamic property subclass use correct get and set methods

The superclass definition is -

classdef calibration ... % Class name

< dynamicprops %% Superclass

% dynamicprops makes handle class

% Creation Properties

properties (SetAccess = immutable)

created = datestr(now, 'yyyymmddTHHMMSS');

author = getenv('username');

end

% Properties

properties

name = '';

end

% Dynamic Property

properties (SetAccess = protected, Hidden = true)

metaDynProp = [];

end

methods

val = get(obj)

set(obj)

end

% Methods

methods

function addCal(obj,calName,calVal)

% ADDCAL adds calibration to a cal object

% Determine calibration type

if isscalar(calVal)

caseNum = 1;

elseif isstruct(calVal) && length(calVal) == 4

caseNum = 2;

elseif isstruct(calVal) && length(calVal) == 6

caseNum = 3;

else

error('Invalid Calibration')

end

% Create Calibration

obj.metaDynProp.(calName) = obj.addprop(calName);

%obj.metaDynProp.(calName).SetAccess = 'private';

switch(caseNum)

case 1 % Scalar case

% Assign Methods

obj.(calName) = scalar;

%obj.metaDynProp.(calName).SetMethod = 'set@scalar';

%obj.metaDynProp.(calName).GetMethod = @scalar.get;

case 2 % Table case

% Assign Methods

case 3 % Map case

% Assign Methods

end

% Set Property

set(obj.(calName),calVal);

end

end

end

The subclass definition is

classdef scalar < calibration

properties

value = [];

end

% Methods

methods

function set(obj,value)

obj.value = value;

end

function value = get(obj)

value = obj.value;

end

end

end

I would like to have the functionality where a calibration can be added such as

x = calibration;

x.addCal('a',1);

Then when x.a is called, the output is 1. However, with the above implementation the output is a scalar object. Also, is there a way to prevent properties from being inherited?

Note that, for datetime formats

• M corresponds to month
• m corresponds to minute
• s corresponds to second
• S corresponds to fractional second

so

created = datestr(now, "yyyymmddTHHMMSS");

as a datetime would be

created = datetime("now", Format="yyyyMMdd'T'HHmmss")

created = datetime
   20220524T174204

You can set property as Private to avoid getting inherited.
