Examples of com.sleepycat.bind.tuple.TupleBinding

com.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 {@link TupleInput} and {@link TupleOutput} objects. Its two abstract methods mustbe implemented by a concrete subclass to convert between tuples and key or data objects.
- {@link #entryToObject(TupleInput)}
- {@link #objectToEntry(Object,TupleOutput)}
