Class UUIDSerializer

java.lang.Object

pt.unl.fct.di.novasys.babel2.channels.serializers.UUIDSerializer

All Implemented Interfaces:

BabelNetworkSerializer<UUID>

@AutoService(BabelNetworkSerializer.class)
public final class UUIDSerializer
extends Object
implements BabelNetworkSerializer<UUID>

Binary serializer for UUID values, encoding each instance as two consecutive 8-byte big-endian longs (most-significant bits followed by least-significant bits), for a total wire size of 16 bytes.

Registered as a BabelNetworkSerializer service provider and discovered at runtime by the SerializerRegistry, making it available for use as a field type inside records annotated with BabelIPMessage.

UUIDSerializer()	Constructs a new UUIDSerializer.

Method Summary

Modifier and Type	Method	Description
UUID	deserialize(io.netty.buffer.ByteBuf in, NodeStore store)	Reads a UUID from the buffer by consuming 16 bytes (two longs).
Class<UUID>	getObjectClass()	Returns UUID.class, which is the type key used by SerializerRegistry to locate this serializer when encoding or decoding UUID fields in generated message serializers.
void	serialize(UUID object, io.netty.buffer.ByteBuf out, NodeStore store)	Encodes object and appends the resulting bytes to out.

UUIDSerializer

public UUIDSerializer()

Constructs a new UUIDSerializer.

Method Details

deserialize

public UUID deserialize(io.netty.buffer.ByteBuf in,
 NodeStore store)

Reads a UUID from the buffer by consuming 16 bytes (two longs).

Specified by:

deserialize in interface BabelNetworkSerializer<UUID>

Parameters:

in - the source buffer

store - the node store context for resolving node components

Returns:

the decoded UUID

serialize

public void serialize(UUID object,
 io.netty.buffer.ByteBuf out,
 NodeStore store)

Description copied from interface: BabelNetworkSerializer

Encodes object and appends the resulting bytes to out.

Specified by:

serialize in interface BabelNetworkSerializer<UUID>

Parameters:

object - the object to serialize

out - the destination buffer

store - the node store context for resolving node components

getObjectClass

public Class<UUID> getObjectClass()

Returns UUID.class, which is the type key used by SerializerRegistry to locate this serializer when encoding or decoding UUID fields in generated message serializers.

Specified by:

getObjectClass in interface BabelNetworkSerializer<UUID>

Returns:

UUID.class
