java.lang.Objectcom.sleepycat.bind.tuple.TupleBinding
An abstract EntryBinding that treats a key or data entry as a
 tuple; it includes predefined bindings for Java primitive types.
 
This class takes care of converting the entries to/from TupleInput and TupleOutput objects.  Its two abstract methods must
 be implemented by a concrete subclass to convert between tuples and key or
 data objects.
For key or data entries which are Java primitive classes (String,
 Integer, etc) getPrimitiveBinding(java.lang.Class) may be used to return a builtin
 tuple binding.  A custom tuple binding for these types is not needed.
