Property inheritance
All built-in, or system, properties assigned to a particular
root class are inherited by all its subclasses. Similarly, all custom
properties added to a class are inherited by all of its subclasses.
If you..
- Add a custom property to a superclass, the property is added to all new and existing subclasses;
however, the property in the existing versions has no value.
- Delete a custom property from a superclass, the property is not deleted from any subclasses.
After you delete the custom property from a superclass, you can manually
delete it from its subclasses.
- Update a custom property on superclass, the change propagates to new versions and subclasses.
The property is not updated in existing subclasses and versions.
- Add an alias ID to a superclass, the alias ID is added to all subclasses.
- Change a property's value for Read Only, Value Required,
or Settability from true to false, the change does not propagate to any subclasses.
Make this change manually.
- Change a property's value for Read Only, Value Required,
or Settability from false to true, the change is propagated to
all subclasses.
- Change the Maximum Length for a string or binary property
, the change propagates to subclasses with a higher
maximum value or where the value was not set.
- Change the Minimum Value or Maximum Value of a property, the change propagates to all subclasses where the
current value is less than the new value, or where a value is not set.
