    public class BigIntegerBinding

extends TupleBinding<BigInteger>

A concrete `TupleBinding` for a `BigInteger` value.

Constructor Summary
`BigIntegerBinding()`

Method Summary
`static void` | `bigIntegerToEntry(BigInteger val, DatabaseEntry entry)` Converts a `BigInteger` value into an entry buffer.
`static BigInteger` | `entryToBigInteger(DatabaseEntry entry)` Converts an entry buffer into a `BigInteger` value.
`BigInteger` | `entryToObject(TupleInput input)` Constructs a key or data object from a `TupleInput` entry.
`protected TupleOutput` | `getTupleOutput(BigInteger object)` Returns an empty TupleOutput instance that will be used by the tuple binding or key creator.
`void` | `objectToEntry(BigInteger object, TupleOutput output)` Converts a key or data object to a tuple entry.

Constructor Detail

### BigIntegerBinding

    public BigIntegerBinding()

Method Detail

### entryToObject

    public BigInteger entryToObject(TupleInput input)

  Description copied from class: `TupleBinding`
  Constructs a key or data object from a `TupleInput` entry.

  Specified by:
    `entryToObject` in class `TupleBinding<BigInteger>`
  Parameters:
    `input` - is the tuple key or data entry.
  Returns:
    the key or data object constructed from the entry.

### objectToEntry

    public void objectToEntry(BigInteger object,
                              TupleOutput output)

  Description copied from class: `TupleBinding`
  Converts a key or data object to a tuple entry.

  Specified by:
    `objectToEntry` in class `TupleBinding<BigInteger>`
  Parameters:
    `object` - is the key or data object.
    `output` - is the tuple entry to which the key or data should be written.

### getTupleOutput

    protected TupleOutput getTupleOutput(BigInteger object)

  Description copied from class: `TupleBase`
  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 `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.

  Overrides:
    `getTupleOutput` in class `TupleBase<BigInteger>`
  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:
    `TupleBase.setTupleBufferSize(int)`

### entryToBigInteger

    public static BigInteger entryToBigInteger(DatabaseEntry entry)

  Converts an entry buffer into a `BigInteger` value.

  Parameters:
    `entry` - is the source entry buffer.
  Returns:
    the resulting value.

### bigIntegerToEntry

    public static void bigIntegerToEntry(BigInteger val,
                                         DatabaseEntry entry)

  Converts a `BigInteger` value into an entry buffer.

  Parameters:
    `val` - is the source value.
    `entry` - is the destination entry buffer.
