Automatic deep copy of handle inside class object.

Is there any way in Matlab to have automatic deep copy of a handle object that is contained inside a class? Occassionally, class methods return values that are a result of a long calculation. It may be inconvenient for the caller to store them and pass them around. It is more convenient to pass the class object instead. I don't want to write:

Obj = Obj.CalculateSomething(...)

which can be inconvenient. Also the function name does not suggest that it is a modifier. I would rather have the class silently cache the calculated values. So I want to have a cache object. For example:

classdef Cache < handle

properties
  Data;
end
  
methods
  function this = Cache(varargin)
    assert(iscellstr(varargin), 'Cache: Inputs must be valid variable names. ');
    numfields = numel(varargin);
    vals = cell(numfields, 1);
    this.Data = cell2struct(vals, varargin(:), 1);
  end
    
  function val = Get(this, fname)
    val = this.Data.(fname);
  end
    
  function Set(this, fname, val)
    this.Data.(fname) = val;
  end
    
end
  
end

Then if I want to cache data inside a class, say DataCruncher, I would write:

classdef DataCruncher

properties (Access = 'private')
  h_cache;
  % ... other properties ...
end

methods:

    function PreciousVals = BigWork(dcobj)
      PreciousVals = dcobj.h_cache.Get('Vals')
      if isempty(PreciousVals)
        % ... Big work ...
        dcobj.h_cache.Set('Vals', PreciousVals);
      end
    end

end

end

Of course the cache is shared by any copies of DataCruncher objects. However it works fine as long as a new Cache object handle is created in any class method that modifies DataCruncher in a way that affects the BigWork() calculation.

But sometimes things get complicated, so I want the h_cache to be deep copied automatically whenever DataCruncher is copied.

Is there any way at all to do this in Matlab? Can Matlab.mixin.Copyable help?

Thank you.
