MATLAB Object-Oriented Programming

• When the loadobj method sets the Address property, it invokes the property set
  method (set.Address), which extracts the substrings required by the
  StreetAddress, City, State, and ZipCode properties.


• The Transient (not saved) property SaveInOldFormat enables you to specify
  whether to save the version 2 object as a struct or an object.

classdef PhoneBookEntry

properties

Name

StreetAddress

City

State

ZipCode

PhoneNumber

end

properties (Constant)

Sep = ', '

end

properties (Dependent, SetAccess=private)

Address

end

properties (Transient)

SaveInOldFormat = false;

end

methods (Static)

function obj = loadobj(s)

if isstruct(s)

obj = PhoneBookEntry;

obj.Name = s.Name;

obj.Address = s.Address;

obj.PhoneNumber = s.PhoneNumber;

else

obj = s;

end

end

end

methods

function address = get.Address(obj)

address = [obj.StreetAddress,obj.Sep,obj.City,obj.Sep,...

obj.State,obj.Sep,obj.ZipCode];

end

function obj = set.Address(obj,address)

addressItems = regexp(address,obj.Sep,'split');

if length(addressItems) == 4
