POSimulate C++ template in MATLAB

copied!<p>I am trying to figure out the best way to create an alternative to the C++ template or the Java generic objects. I have wanted to do this several times in the past for several different reasons, however right now what I want to do is related to creating the saveobj and loadobj functions for several related classes. The idea is that I want to have a generic set of routines to create a default struct and then manipulate that a little bit farther to get the structs the way I want them.</p> <p>I cannot simply use an external function because I need access to all the public (not a problem) and protected (problem) non-transient properties of an object in order to create the loadobj and saveobj.</p> <p>Then I considered using an abstract interface. However, using an abstract interface leaves me with the same problem; identical, copy an pasted code floating around in all of my object files. So then I thought of using some sort of full blown object combined with multiple inheritance (Most of my objects are already inheriting from a basic concretion of interfaces). I thought using a superclass would allow me to expose the subclass protected properties, but it doesn't seem to work that way. Any suggestions?</p> <p>Here is a sample of the multiple inheritance approach (the closest thing I have so far) for the save obj approach.</p> <p>Serializer.m</p> <pre><code>% Serializer.m classdef Serializer methods function [saveObj] = saveobj( obj ) % Get metadata about the Object meta = metaclass( obj ); meta = meta.PropertyList; for p = meta' if p.Transient | p.Dependent continue; % Only serialize the correct fields end saveobj.(p.Name) = { obj.(p.Name) }; % Serialize end % for ( property ) end % function ( saveobj ) end % methods end % classdef ( Serializer ) </code></pre> <p>TestSerializerA.m</p> <pre><code>% TestSerializerA.m classdef TestSerializerA < Serializer properties PropA = 'a'; end % properties ( public ) properties( Access = protected ) HiddenA = 'ha' end % properties ( protected ) end % classdef ( TestSerializerA ) </code></pre> <p>TestSerializerB.m</p> <pre><code>% TestSerializerB.m classdef TestSerializerB < TestSerializerA & Serializer properties PropB = 'b' end properties( Access = protected ) HiddenB = 'hb'; end % properties ( protected ) end % classdef ( TestSerializerB ) </code></pre>
