The LTPDA toolbox restrict access of the properties.
The get access is 'public' and thus it is possible to get the values with the dot-command (similar to structures).
For example:The set access is 'protected' and thus it is only possible to assign a value to a property with a set-method.
val = obj.prop(2).prop;
For example: obj2 = obj1.setName('my name') % This command creates a copy of obj1 (obj1 ~= obj2) obj.setName('my name'); % This command applies to obj
