All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, ContainerMapping, ArrayCollectionMapping

Direct Known Subclasses:

EISCompositeCollectionMapping, ObjectArrayMapping, XMLCompositeCollectionMapping

public abstract class AbstractCompositeCollectionMapping
extends AggregateMapping
implements ContainerMapping, ArrayCollectionMapping

Define an embedded collection of objects. This is used in structured data-types, such as EIS, NoSQL and object-relational Array (varray, nested table) data-types. The target objects must be aggregate (embedded) and are stored with the parent object.

getAttributeValueFromBackupClone

protected java.lang.Object getAttributeValueFromBackupClone(java.lang.Object backupClone)

Return the appropriate attribute value. This method is a hack to allow the aggregate collection subclass to override.... The intent is to return the aggregate object in the backup clone that corresponds to the one in the working copy. Since we don't know which element in the backup clone collection corresponds any given element in the working copy collection (there is no "primary key"); we simply return null, which will cause a new, empty, instance to be built and used for comparison.
