EntryBinding<java.lang.Short>
public class ShortBinding extends TupleBinding<java.lang.Short>
TupleBinding
for a Short
primitive
wrapper or a short
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 |
---|---|---|
java.lang.Short |
entryToObject(TupleInput input) |
Constructs a key or data object from a
TupleInput entry. |
static short |
entryToShort(DatabaseEntry entry) |
Converts an entry buffer into a simple
short value. |
protected TupleOutput |
getTupleOutput(java.lang.Short object) |
Returns an empty TupleOutput instance that will be used by the tuple
binding or key creator.
|
void |
objectToEntry(java.lang.Short object,
TupleOutput output) |
Converts a key or data object to a tuple entry.
|
static void |
shortToEntry(short val,
DatabaseEntry entry) |
Converts a simple
short value into an entry buffer. |

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.
