Detailed Description

An abstract EntityBinding that treats an entity's key entry and data entry as tuples.

This class takes care of converting the entries to/from TupleInput and TupleOutput objects. Its three abstract methods must be implemented by a concrete subclass to convert between tuples and entity objects.

• entryToObject(TupleInput,TupleInput)
• objectToKey(Object,TupleOutput)
• objectToData(Object,TupleOutput)

Member Function Documentation

abstract Object com::sleepycat::bind::tuple::TupleTupleBinding::entryToObject (  TupleInput  keyInput, TupleInput  dataInput )  [pure virtual]

Constructs an entity object from TupleInput key and data entries. Parameters: keyInput  is the TupleInput key entry object. dataInput  is the TupleInput data entry object. Returns: the entity object constructed from the key and data. Implemented in com::sleepycat::bind::tuple::TupleTupleMarshalledBinding.

Object com::sleepycat::bind::tuple::TupleTupleBinding::entryToObject (  DatabaseEntry  key, DatabaseEntry  data )  [inline]

Converts key and data entry buffers into an entity Object. Parameters: key  is the source key entry. data  is the source data entry. Returns: the resulting Object. Implements com::sleepycat::bind::EntityBinding. Definition at line 41 of file TupleTupleBinding.java.

abstract void com::sleepycat::bind::tuple::TupleTupleBinding::objectToData (  Object  object, TupleOutput  output )  [pure virtual]

Extracts a key tuple from an entity object. Parameters: object  is the entity object. output  is the TupleOutput to which the data should be written. Implemented in com::sleepycat::bind::tuple::TupleTupleMarshalledBinding.

void com::sleepycat::bind::tuple::TupleTupleBinding::objectToData (  Object  object, DatabaseEntry  data )  [inline]

Extracts the data entry from an entity Object. Parameters: object  is the source Object. data  is the destination entry buffer. Implements com::sleepycat::bind::EntityBinding. Definition at line 56 of file TupleTupleBinding.java. References com::sleepycat::bind::tuple::TupleBase::getTupleOutput(), and com::sleepycat::bind::tuple::TupleBase::outputToEntry().

abstract void com::sleepycat::bind::tuple::TupleTupleBinding::objectToKey (  Object  object, TupleOutput  output )  [pure virtual]

Extracts a key tuple from an entity object. Parameters: object  is the entity object. output  is the TupleOutput to which the key should be written. Implemented in com::sleepycat::bind::tuple::TupleTupleMarshalledBinding.

void com::sleepycat::bind::tuple::TupleTupleBinding::objectToKey (  Object  object, DatabaseEntry  key )  [inline]

Extracts the key entry from an entity Object. Parameters: object  is the source Object. key  is the destination entry buffer. Implements com::sleepycat::bind::EntityBinding. Definition at line 48 of file TupleTupleBinding.java. References com::sleepycat::bind::tuple::TupleBase::getTupleOutput(), and com::sleepycat::bind::tuple::TupleBase::outputToEntry().
