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.

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.
