The class specifies an initial value of 7 for the PropOne property. Therefore, if you create

an object and assign the property value of 7 , there is no need to trigger the PreSet

event. However, the getPropOne method is called to get the current value of the

property to compare to the assigned vale.

obj = AbortTheSet;

obj.PropOne = 7;

get.PropOne called

If you specify a value other than 7 , then MATLAB performs these steps:

• Gets the current property value


• Triggers the PreSet event


• Sets the property to the assigned value


• Triggers the PostSet event

obj = AbortTheSet;

obj.PropOne = 9;
