# SecondClass Interface

marks objects as second class objects.

public interface SecondClass : Db4oType

#### Remarks

marks objects as second class objects.
Currently this interface is for internal use only to help discard com.db4o.config.Entry objects in the Defragment process.
For future versions this interface is planned to mark objects that:
- are not to be held in the reference mechanism
- should always be activated with their parent objects
- should always be deleted with their parent objects
- should always be deleted if they are not referenced any longer.

#### Requirements

Namespace: com.db4o.types

Assembly: db4o (in db4o.dll)
