java.lang.Objectcom.sleepycat.db.HeapRecordId
public class HeapRecordId
Content used for the key in a Heap database record. Berkeley DB creates this value for you when you create a record in a Heap database. You should never create this structure yourself; Berkeley DB must create it for you. This structure is returned in the key DatabaseEntry parameter of the method that you use to add a record to the Heap database.
