java.lang.Objectcom.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.

TupleSerialBinding(ClassCatalog classCatalog,
Class baseClass) Creates a tuple-serial entity binding. |

TupleSerialBinding(SerialBinding dataBinding)
Creates a tuple-serial entity binding. |
