Class TupleTupleMarshalledKeyCreator

public class TupleTupleMarshalledKeyCreator extends TupleTupleKeyCreator

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.

Constructor Summary
	TupleTupleMarshalledKeyCreator(TupleTupleMarshalledBinding binding, String keyName) Creates a tuple-tuple marshalled key creator.

Method Summary
boolean	createSecondaryKey(TupleInput primaryKeyInput, TupleInput dataInput, TupleOutput indexKeyOutput)
boolean	nullifyForeignKey(TupleInput dataInput, TupleOutput dataOutput)
