MATLAB Object-Oriented Programming

Change Effect

Change property attribute

value

Applies changes to existing objects of the class.

Some cases require transitional steps:

• Abstract — Existing objects of a class that becomes
  abstract cannot be updated. Delete these objects.


• Access — Changes to the public, protected, or
  private property access settings affect access to
  existing objects.

Changes to the access lists do not change existing

objects. However, if you add classes to the access

list, instances of those classes have access to this

property. If you remove classes from the access list,

objects of those classes no longer have access to this

property.

• Dependent — If changed to true, existing objects
  no longer store property values. If you want to query
  the property value, add a property get method for
  the property.


• Transient — If changed to true, objects already
  saved, reload this property value. If changed to
  false, objects already saved reload this property
  using the default value.

Updates to Method Definitions

When you change the definition of class methods, MATLAB changes the affected class

member in existing objects as follows.

Change Effect

Add method You can call the new method on existing objects of the

class.

Modify method Modifications are available to existing objects.

Remove method You can on longer call deleted method on existing

objects.
