An `EntryBinding` that treats a record number key entry as a `Long` key object.

Record numbers are returned as `Long` objects, although on input any `Number` object may be used.

Constructor Summary
`RecordNumberBinding()` Creates a byte array binding.

Method Summary
`Long` | `entryToObject(DatabaseEntry entry)` Converts a entry buffer into an Object.
`static long` | `entryToRecordNumber(DatabaseEntry entry)` Utility method for use by bindings to translate a entry buffer to an record number integer.
`void` | `objectToEntry(Object object, DatabaseEntry entry)` Converts an Object into a entry buffer.
`static void` | `recordNumberToEntry(long recordNumber, DatabaseEntry entry)` Utility method for use by bindings to translate a record number integer to a entry buffer.
