java.lang.Object com.sleepycat.bind.tuple.TupleBase com.sleepycat.bind.serial.TupleSerialBinding
An abstract EntityBinding
that treats an entity's key entry as
a tuple and its data entry as a serialized object.
This class takes care of serializing and deserializing the data entry,
and converting the key entry to/from TupleInput
and TupleOutput
objects. Its three abstract methods must be implemented by a
concrete subclass to convert these objects to/from an entity object.
