MATLAB Object-Oriented Programming

• When MATLAB copies a value object (any object that is not a handle), MATLAB does
  not call the set or get method when copying property values from one object to
  another.


• Any assignment made to a property value that is the same as the current value when
  the property’s AbortSet attribute is true. See “Assignment When Property Value Is
  Unchanged” on page 11-44 for more information on this attribute.

Setting Property Value in Constructor

Setting a property value in the constructor causes the property set method to be called.

For example, the PropertySetMethod class defines a property set method for the Prop1

property.

classdef PropertySetMethod

properties

Prop1 = "Default String"

end

methods

function obj = PropertySetMethod( str )

if nargin > 0

obj.Prop1 = str;

end

end

function obj = set.Prop1(obj,str)

obj.Prop1 = str;

fprintf( 'set.Prop1 method called. Prop1 = %s\n', obj.Prop1 );

end

end

end

If you call the class constructor with no input arguments, MATLAB does not call the

set.Prop1 method.

>> o = PropertySetMethod

o =

PropertySetMethod with properties:

Prop1: "Default String"
