public interface RowLocation
extends DataValueDescriptor, CloneableObject

Holds the location of a row within a given conglomerate. A row location is not valid except in the conglomerate from which it was obtained. They are used to identify rows for fetches, deletes, and updates through a conglomerate controller.

See the conglomerate implementation specification for information about the conditions under which a row location remains valid.
