EntryBinding<java.lang.Byte>
public class ByteBinding extends TupleBinding<java.lang.Byte>
TupleBinding
for a Byte
primitive
wrapper or a byte
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. The easiest way to
obtain a binding instance is with the TupleBinding.getPrimitiveBinding(java.lang.Class<T>)
method.Constructor | Description |

Modifier and Type | Method | Description |
---|---|---|
static void |
byteToEntry(byte val,
DatabaseEntry entry) |
Converts a simple
byte value into an entry buffer. |
static byte |
entryToByte(DatabaseEntry entry) |
Converts an entry buffer into a simple
byte value. |
java.lang.Byte |
entryToObject(TupleInput input) |
Constructs a key or data object from a
TupleInput entry. |
protected TupleOutput |
getTupleOutput(java.lang.Byte object) |
Returns an empty TupleOutput instance that will be used by the tuple
binding or key creator.
|
void |
objectToEntry(java.lang.Byte object,
TupleOutput output) |
Converts a key or data object to a tuple entry.

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.
