java.lang.Object
   org.jpox.identity.DatastoreUniqueOID

DatastoreUniqueOID
public class DatastoreUniqueOID implements java.io.Serializable,OID(Code)
Identity for use with datastore-identity where the datastore provides a unique "identity" key per object and hence doesn't need the class name. The behaviour of this class is governed by JDO spec 5.4.3. Main benefit over OIDImpl is size.
version:
   $Revision: 1.1 $


Field Summary
final public  longkey
     The key value.

Constructor Summary
public  DatastoreUniqueOID()
     Creates an OID with no value.
public  DatastoreUniqueOID(long key)
     Constructor taking the long form of the key.
public  DatastoreUniqueOID(String str)
     Constructs an OID from its string representation that is consistent with the output of toString().

Method Summary
public  booleanequals(Object obj)
     Equality operator.
public  longgetKey()
     Convenience accessor for the long form of the key.
public  ObjectgetKeyValue()
     Accessor for the key value.
public  StringgetPcClass()
