Detailed Description

A concrete TupleSerialBinding that delegates to the MarshalledTupleKeyEntity interface of the entity class.

The MarshalledTupleKeyEntity interface must be implemented by the entity class to convert between the key/data entry and entity object.

The binding is "tricky" in that it uses the entity class for both the stored data entry and the combined entity object. To do this, the entity's key field(s) are transient and are set by the binding after the data object has been deserialized. This avoids the use of a "data" class completely.

Constructor & Destructor Documentation

com::sleepycat::bind::serial::TupleSerialMarshalledBinding::TupleSerialMarshalledBinding (  ClassCatalog  classCatalog, Class  baseClass )  [inline]

Creates a tuple-serial marshalled binding object. Parameters: classCatalog  is the catalog to hold shared class information and for a database should be a StoredClassCatalog. baseClass  is the base class for serialized objects stored using this binding -- all objects using this binding must be an instance of this class. Definition at line 44 of file TupleSerialMarshalledBinding.java.

com::sleepycat::bind::serial::TupleSerialMarshalledBinding::TupleSerialMarshalledBinding (  SerialBinding  dataBinding  )  [inline]

Creates a tuple-serial marshalled binding object. Parameters: dataBinding  is the binding used for serializing and deserializing the entity object. Definition at line 56 of file TupleSerialMarshalledBinding.java.

Object com::sleepycat::bind::serial::TupleSerialMarshalledBinding::entryToObject (  TupleInput  tupleInput, Object  javaInput )  [inline, virtual]

Constructs an entity object from TupleInput key entry and deserialized data entry objects. Parameters: keyInput  is the TupleInput key entry object. dataInput  is the deserialized data entry object. Returns: the entity object constructed from the key and data. Implements com::sleepycat::bind::serial::TupleSerialBinding. Definition at line 62 of file TupleSerialMarshalledBinding.java.

Object com::sleepycat::bind::serial::TupleSerialMarshalledBinding::objectToData (  Object  object  )  [inline, virtual]

Extracts a data object from an entity object. Parameters: object  is the entity object. Returns: the deserialized data object. Implements com::sleepycat::bind::serial::TupleSerialBinding. Definition at line 86 of file TupleSerialMarshalledBinding.java.

void com::sleepycat::bind::serial::TupleSerialMarshalledBinding::objectToKey (  Object  object, TupleOutput  output )  [inline, virtual]

Extracts a key tuple from an entity object. Parameters: object  is the entity object. keyOutput  is the TupleOutput to which the key should be written.
