java.lang.Object | +--com.sleepycat.bdb.bind.tuple.TupleBinding
An abstract tuple binding for tuple keys or values. This class takes care of
 converting the data to/from TupleInput and TupleOutput
 objects.  Its two abstract methods must be implemented by a concrete
 subclass to convert between tuples and key or value objects.
 
For keys or values which are Java primitive classes (String, Integer,
 etc) getPrimitiveBinding(java.lang.Class, com.sleepycat.bdb.bind.tuple.TupleFormat) may be used to return a builtin tuple
 binding.  A custom tuple binding for these types is not needed.
| Constructor Summary | |
| TupleBinding(TupleFormat format)Creates a tuple binding. | |
| Method Summary | |
|  Object | dataToObject(DataBuffer data)Converts a data buffer into an Object. | 
| abstract  Object | dataToObject(TupleInput input)Constructs a key or value object from TupleInputdata. | 
|  DataFormat | getDataFormat()Returns the format used for the data of this binding. | 
| static TupleBinding | getPrimitiveBinding(Class cls,
                    TupleFormat format)Creates a tuple binding for a primitive Java class. | 
|  void | objectToData(Object object,
             DataBuffer data)Converts an Object into a data buffer. | 
| abstract  void | objectToData(Object object,
