public class FloatBinding
extends TupleBinding<Float>

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.getPrimitiveBinding(java.lang.Class) method.

Method Detail

entryToObject

public Float entryToObject(TupleInput input)
Description copied from class: TupleBinding
Constructs a key or data object from a TupleInput entry.

Specified by:
entryToObject in class TupleBinding<Float>
Parameters:
input - is the tuple key or data entry.
Returns:
the key or data object constructed from the entry.

objectToEntry

public void objectToEntry(Float object,
                          TupleOutput output)
Description copied from class: TupleBinding
Converts a key or data object to a tuple entry.

Specified by:
objectToEntry in class TupleBinding<Float>
Parameters:
object - is the key or data object.
output - is the tuple entry to which the key or data should be written.

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.

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.
