MATLAB Programming

Example — Assets and Asset Subclasses
function val = get(a, propName)
% GET Get asset properties from the specified object
% and return the value
switch propName
case 'Descriptor'
val = a.descriptor;
case 'Date'
val = a.date;
case 'CurrentValue'
val = a.currentValue;
otherwise
error([propName,' Is not a valid asset property'])
end
This function accepts an object and a property name and uses a switch
statement to determine which field to access. This method is called by the
subclass get methods when accessing the data in the inherited properties.
See“TheStockgetMethod”onpage9-52foranexample.
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
propertyArgIn = varargin;
while length(propertyArgIn) >= 2,
prop = propertyArgIn{1};
val = propertyArgIn{2};
propertyArgIn = propertyArgIn(3:end);
switch prop
case 'Descriptor'
a.descriptor = val;
case 'Date'
a.date = val;
case 'CurrentValue'
a.currentValue = val;
otherwise
