Detailed Description

A concrete TupleBinding for a Short primitive wrapper or a short primitive.

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 method.

Member Function Documentation

Object com::sleepycat::bind::tuple::ShortBinding::entryToObject (  TupleInput  input  )  [inline, virtual]

Constructs a key or data object from a TupleInput entry. Parameters: input  is the tuple key or data entry. Returns: the key or data object constructed from the entry. Implements com::sleepycat::bind::tuple::TupleBinding. Definition at line 34 of file ShortBinding.java. References com::sleepycat::bind::tuple::TupleInput::readShort().

static short com::sleepycat::bind::tuple::ShortBinding::entryToShort (  DatabaseEntry  entry  )  [inline, static]

Converts an entry buffer into a simple short value. Parameters: entry  is the source entry buffer. Returns: the resulting value. Definition at line 58 of file ShortBinding.java. References com::sleepycat::bind::tuple::TupleBase::entryToInput().

TupleOutput com::sleepycat::bind::tuple::ShortBinding::getTupleOutput (  Object  object  )  [inline, protected]

Returns an empty TupleOutput instance that will be used by the tuple binding or key creator. The default implementation of this method creates a new TupleOutput with an initial buffer size that can be changed using the setTupleBufferSize 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 com.sleepycat.util.FastOutputStream#reset method before each use. Parameters: object  is the object to be written to the tuple output, and may be used by subclasses to determine the size of the output buffer. Returns: an empty TupleOutput instance. See also: setTupleBufferSize Reimplemented from com::sleepycat::bind::tuple::TupleBase. Definition at line 46 of file ShortBinding.java.

void com::sleepycat::bind::tuple::ShortBinding::objectToEntry (  Object  object, TupleOutput  output )  [inline, virtual]

Converts a key or data object to a tuple entry. Parameters: object  is the key or data object. output  is the tuple entry to which the key or data should be written. Implements com::sleepycat::bind::tuple::TupleBinding. Definition at line 40 of file ShortBinding.java. References com::sleepycat::bind::tuple::TupleOutput::writeShort().

static void com::sleepycat::bind::tuple::ShortBinding::shortToEntry (  short  val, DatabaseEntry  entry )  [inline, static]

Converts a simple short value into an entry buffer. Parameters: val  is the source value. entry  is the destination entry buffer. Definition at line 70 of file ShortBinding.java. References com::sleepycat::bind::tuple::TupleBase::outputToEntry().
