Examples of MarshalledTupleKeyEntity

com.sleepycat.bdb.bind.tuple.MarshalledTupleKeyEntity
A marshalling interface implemented by entity classes that have tuple data keys. Since MarshalledTupleKeyEntity objects are instantiated by Java serialization, no particular contructor is required.
Note that a marshalled tuple key extractor is somewhat less efficient than a non-marshalled key tuple extractor because more conversions are needed. A marshalled key extractor must convert the data to an object in order to extract the key data, while an unmarshalled key extractor does not.

com.sleepycat.bind.tuple.MarshalledTupleKeyEntity
A marshalling interface implemented by entity classes that represent keys as tuples. Since MarshalledTupleKeyEntity objects are instantiated using Java deserialization, no particular constructor is required by classes that implement this interface.
Note that a marshalled tuple key extractor is somewhat less efficient than a non-marshalled key tuple extractor because more conversions are needed. A marshalled key extractor must convert the entry to an object in order to extract the key fields, while an unmarshalled key extractor does not.
