Class ClusterSingletonMessageSerializer

java.lang.Object

akka.serialization.SerializerWithStringManifest

akka.cluster.singleton.protobuf.ClusterSingletonMessageSerializer

All Implemented Interfaces:

BaseSerializer, Serializer

public class ClusterSingletonMessageSerializer
extends SerializerWithStringManifest
implements BaseSerializer

INTERNAL API: Serializer of ClusterSingleton messages. It is actually not using protobuf, but if we add more messages to the ClusterSingleton we want to make protobuf representations of them.

Method Summary

Modifier and Type	Method and Description
java.lang.Object	fromBinary(byte[] bytes, java.lang.String manifest) Produces an object from an array of bytes, with an optional type-hint; the class should be loaded using ActorSystem.dynamicAccess.
int	identifier() Completely unique value to identify this implementation of Serializer, used to optimize network traffic.
java.lang.String	manifest(java.lang.Object obj) Return the manifest (type hint) that will be provided in the fromBinary method.
ExtendedActorSystem	system() Actor system which is required by most serializer implementations.
byte[]	toBinary(java.lang.Object obj) Serializes the given object into an Array of Byte

Method Detail

identifier

public int identifier()

Description copied from class: SerializerWithStringManifest

Completely unique value to identify this implementation of Serializer, used to optimize network traffic. Values from 0 to 40 are reserved for Akka internal usage.

identifier in interface Serializer

Specified by:

identifier in class SerializerWithStringManifest

Returns:

system

public ExtendedActorSystem system()

Description copied from interface: BaseSerializer

Actor system which is required by most serializer implementations.

Specified by:

system in interface BaseSerializer

Returns:

(undocumented)

manifest

public java.lang.String manifest(java.lang.Object obj)

Description copied from class: SerializerWithStringManifest

Return the manifest (type hint) that will be provided in the fromBinary method. Use "" if manifest is not needed.

Specified by:

manifest in class SerializerWithStringManifest

Parameters:

obj - (undocumented)

Returns:

(undocumented)

toBinary

public byte[] toBinary(java.lang.Object obj)

Description copied from class: SerializerWithStringManifest

Serializes the given object into an Array of Byte

Specified by:

toBinary in interface Serializer

Specified by:

toBinary in class SerializerWithStringManifest

Parameters:

obj - (undocumented)

Returns:

(undocumented)

fromBinary

public java.lang.Object fromBinary(byte[] bytes,
                                   java.lang.String manifest)

Description copied from class: SerializerWithStringManifest

Produces an object from an array of bytes, with an optional type-hint; the class should be loaded using ActorSystem.dynamicAccess.

It's recommended to throw java.io.NotSerializableException in fromBinary if the manifest is unknown. This makes it possible to introduce new message types and send them to nodes that don't know about them. This is typically needed when performing rolling upgrades, i.e. running a cluster with mixed versions for while. NotSerializableException is treated as a transient problem in the TCP based remoting layer. The problem will be logged and message is dropped. Other exceptions will tear down the TCP connection because it can be an indication of corrupt bytes from the underlying transport.
