Class FloatBinding

public class FloatBinding extends TupleBinding

A concrete TupleBinding for a Float primitive wrapper or a float 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 SortedFloatBinding.

There are two ways to use this class:

  1. 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.
  2. 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 Detail

entryToFloat

public static float entryToFloat(DatabaseEntry entry)
Converts an entry buffer into a simple float value.

Parameters: entry is the source entry buffer.

Returns: the resulting value.

entryToObject

floatToEntry

public static void floatToEntry(float val, DatabaseEntry entry)
Converts a simple float value into an entry buffer.

Parameters: val is the source value. entry is the destination entry buffer.

getTupleOutput

protected TupleOutput getTupleOutput(Object object)

objectToEntry

public void objectToEntry(Object object, TupleOutput output)
