Examples of org.apache.derby.iapi.types.RowLocation

org.apache.derby.iapi.types.RowLocation
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.
