public class SortedFloatBinding extends TupleBinding<java.lang.Float>
TupleBinding
for a sorted Float
primitive wrapper or sorted a float
primitive.
There are two ways to use this class:
com.sleepycat.db
package directly, the static
methods in this class can be used to convert between primitive values and
DatabaseEntry
objects.com.sleepycat.collections
package, an instance of
this class can be used with any stored collection.Constructor and Description |

static float |
entryToFloat(DatabaseEntry entry)
Converts an entry buffer into a simple
float value. |
java.lang.Float |
entryToObject(TupleInput input)
Constructs a key or data object from a
TupleInput entry. |
static void |
floatToEntry(float val,
DatabaseEntry entry)
Converts a simple
float value into an entry buffer. |
protected TupleOutput |
getTupleOutput(java.lang.Float object)
Returns an empty TupleOutput instance that will be used by the tuple
binding or key creator.

TupleBase
The default implementation of this method creates a new TupleOutput
with an initial buffer size that can be changed using the TupleBase.setTupleBufferSize(int)
method.
This method may be overridden to return a TupleOutput instance. For
example, an instance per thread could be created and returned by this
method. If a TupleOutput instance is reused, be sure to call its
FastOutputStream.reset()
method before each
use.
