The Asset set Method

The asset class set method is called by subclass set methods. This method accepts an asset object and variable length argument list of property name/property value pairs and returns the modified object.

• function a = set(a,varargin)
  % SET Set asset properties and return the updated object
  property_argin = varargin;
  while length(property_argin) >= 2,
      prop = property_argin{1};
      val = property_argin{2};
      property_argin = property_argin(3:end);
      switch prop
      case 'Descriptor'
          a.descriptor = val;
      case 'Date'
          a.date = val;
      case 'CurrentValue'
          a.current_value = val;
      otherwise
          error('Asset properties: Descriptor, Date, CurrentValue')
      end
  end
  

Subclass set methods call the asset set method and require the capability to return the modified object since MATLAB does not support passing arguments by reference. See The Stock set Method for an example.
