SortedDoubleBinding

Class SortedDoubleBinding

public class SortedDoubleBinding extends TupleBinding

A concrete TupleBinding for a Double primitive wrapper or a double primitive.

This class produces byte array values that by default (without a custom comparator) sort correctly, including sorting of negative values. Therefore, this class should normally be used instead of DoubleBinding which does not by default support sorting of negative values. Please note that:

The byte array (stored) formats used by DoubleBinding and SortedDoubleBinding are different and incompatible. They are not interchangable once data has been stored.
An instance of DoubleBinding, not SortedDoubleBinding, is returned by TupleBinding method. Therefore, to use SortedDoubleBinding, TupleBinding should not be called.

There are two ways to use this class:

When using the com.sleepycat.db package directly, the static methods in this class can be used to convert between primitive values and DatabaseEntry objects.
When using the com.sleepycat.collections package, an instance of this class can be used with any stored collection.

Method Summary
static void	doubleToEntry(double val, DatabaseEntry entry) Converts a simple `double` value into an entry buffer.
static double	entryToDouble(DatabaseEntry entry) Converts an entry buffer into a simple `double` value.
Object	entryToObject(TupleInput input)
protected TupleOutput	getTupleOutput(Object object)
void	objectToEntry(Object object, TupleOutput output)
