classdef SCDclass_mdsparenum < SCDclass_mdspar
    % A string enumerated MDS parameter, for uint16 enum codes
    % 
    % behavior in MATLAB:
    %  if a string match between MDS string and matlab num string is 
    %  asserted, the enum choice is loaded into the tun parameter
    %  if not a warning is issued and the param is left untouched
    % behavior in MARTe2:
    %  the same than before but the enum map is used to load the
    %  equivalent uint16 code on the MARTe2 side tunable parameter
    %  if a string match is not detected, the parameter is invalidated
