Package com.sleepycat.bind.tuple

Class SortedBigDecimalBinding

java.lang.Object

com.sleepycat.bind.tuple.TupleBase<E>

com.sleepycat.bind.tuple.TupleBinding<java.math.BigDecimal>

com.sleepycat.bind.tuple.SortedBigDecimalBinding

All Implemented Interfaces:

EntryBinding<java.math.BigDecimal>

public class SortedBigDecimalBinding
extends TupleBinding<java.math.BigDecimal>

A concrete TupleBinding for a sorted BigDecimal value.

There are two ways to use this class:

1. When using the com.sleepycat.db package directly, the static methods in this class can be used to convert between primitive values and DatabaseEntry objects.
2. When using the com.sleepycat.collections package, an instance of this class can be used with any stored collection.

Method Detail

entryToObject

public java.math.BigDecimal entryToObject(TupleInput input)

Description copied from class: TupleBinding

Constructs a key or data object from a TupleInput entry.

Specified by:

entryToObject in class TupleBinding<java.math.BigDecimal>

Parameters:

input - is the tuple key or data entry.

Returns:

the key or data object constructed from the entry.

objectToEntry

public void objectToEntry(java.math.BigDecimal object,
                          TupleOutput output)

Description copied from class: TupleBinding

Converts a key or data object to a tuple entry.

Specified by:

objectToEntry in class TupleBinding<java.math.BigDecimal>

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(java.math.BigDecimal 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<java.math.BigDecimal>

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)

entryToBigDecimal

public static java.math.BigDecimal entryToBigDecimal(DatabaseEntry entry)

Converts an entry buffer into a BigDecimal value.

Parameters:

entry - is the source entry buffer.

Returns:

the resulting value.

bigDecimalToEntry

public static void bigDecimalToEntry(java.math.BigDecimal val,
                                     DatabaseEntry entry)

Converts a BigDecimal value into an entry buffer.

Parameters:

val - is the source value.

entry - is the destination entry buffer.
