- org.eclipse.persistence.descriptors.copying.AbstractCopyPolicy

All Implemented Interfaces:

Serializable, Cloneable, CopyPolicy

Direct Known Subclasses:

CloneCopyPolicy, InstantiationCopyPolicy, PersistenceEntityCopyPolicy
```
public abstract class AbstractCopyPolicy
extends Object
implements CopyPolicy
```
Purpose: Allows customization of how an object is cloned. This class defines common behavior that allows a subclass to be used and set on a descriptor to provide a special cloning routine for how an object is cloned in a unit of work.
