DoubleBinding

Class DoubleBinding

public class DoubleBinding extends TupleBinding

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

Note: This class produces byte array values that by default (without a custom comparator) do not sort correctly for negative values. Only non-negative values are sorted correctly by default. To sort all values correctly by default, use SortedDoubleBinding.

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. The easiest way to obtain a binding instance is with the TupleBinding method.

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)
