All Superinterfaces:

AttributeSerializer<V>

All Known Implementing Classes:

BooleanSerializer, ByteSerializer, CharacterSerializer, DateSerializer, DoubleSerializer, EnumSerializer, FloatSerializer, IntegerSerializer, LongSerializer, ShortSerializer, StringSerializer, UUIDSerializer

public interface OrderPreservingSerializer<V>
extends AttributeSerializer<V>

Interface that extends AttributeSerializer to provide a serialization that is byte order preserving, i.e. the order of the elements (as given by its Comparable implementation) corresponds to the natural order of the serialized byte representation representation.

Method Summary

Modifier and Type	Method and Description
V	readByteOrder(ScanBuffer buffer) Reads an attribute from the given ReadBuffer assuming it was written in byte order.
void	writeByteOrder(WriteBuffer buffer, V attribute) Writes the attribute value to the given WriteBuffer such that the byte order of the result is equal to the natural order of the attribute.

Method Detail

readByteOrder

V readByteOrder(ScanBuffer buffer)

Reads an attribute from the given ReadBuffer assuming it was written in byte order.

It is expected that this read operation adjusts the position in the ReadBuffer to after the attribute value.

Parameters:

buffer - ReadBuffer to read attribute from

Returns:

Read attribute

writeByteOrder

void writeByteOrder(WriteBuffer buffer,
                    V attribute)

Writes the attribute value to the given WriteBuffer such that the byte order of the result is equal to the natural order of the attribute.

It is expected that this write operation adjusts the position in the WriteBuffer to after the attribute value.

Parameters:

buffer - WriteBuffer to write attribute to

attribute - Attribute to write to WriteBuffer
