java.lang.Objectcom.sleepycat.bind.tuple.TupleBase<E>
com.sleepycat.bind.tuple.TupleTupleKeyCreator<E>
com.sleepycat.bind.tuple.TupleTupleMarshalledKeyCreator<E>
public class TupleTupleMarshalledKeyCreator<E extends MarshalledTupleEntry & MarshalledTupleKeyEntity>
A concrete key creator that works in conjunction with a TupleTupleMarshalledBinding.  This key creator works by calling the
 methods of the MarshalledTupleKeyEntity interface to create and
 clear the index key.
 
Note that a marshalled tuple key creator is somewhat less efficient than a non-marshalled key tuple creator because more conversions are needed. A marshalled key creator must convert the entry to an object in order to create the key, while an unmarshalled key creator does not.

TupleTupleKeyCreator
createSecondaryKey in class TupleTupleKeyCreator<E extends MarshalledTupleEntry & MarshalledTupleKeyEntity>primaryKeyInput - is the TupleInput for the primary key
 entry.dataInput - is the TupleInput for the data entry.indexKeyOutput - is the destination index key tuple.
public boolean nullifyForeignKey(TupleInput dataInput,

TupleTupleKeyCreatorThe secondary key should be output or removed by this method such
 that TupleTupleKeyCreator.createSecondaryKey(com.sleepycat.db.SecondaryDatabase, com.sleepycat.db.DatabaseEntry, com.sleepycat.db.DatabaseEntry, com.sleepycat.db.DatabaseEntry) will return false.  Other fields in the
 data object should remain unchanged.
nullifyForeignKey in class TupleTupleKeyCreator<E extends MarshalledTupleEntry & MarshalledTupleKeyEntity>dataInput - is the TupleInput for the data entry.dataOutput - is the destination TupleOutput.
