akka$serialization$BaseSerializer$_setter_$identifier_$eq

protected void akka$serialization$BaseSerializer$_setter_$identifier_$eq(int x$1)

Description copied from interface: BaseSerializer

Globally unique serialization identifier configured in the reference.conf.

See Serializer.identifier.

Specified by:

akka$serialization$BaseSerializer$_setter_$identifier_$eq in interface BaseSerializer

compress

public byte[] compress(akka.protobufv3.internal.MessageLite msg)

decompress

public byte[] decompress(byte[] bytes)

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.

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.

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.

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

metricSelectorFromProto

public MetricsSelector metricSelectorFromProto(ClusterMetricsMessages.MetricsSelector selector)

mixMetricSelectorFromBinary

public MixMetricsSelector mixMetricSelectorFromBinary(byte[] bytes)

system

public ExtendedActorSystem system()

Description copied from interface: BaseSerializer

Actor system which is required by most serializer implementations.

Specified by:

system in interface BaseSerializer

toBinary

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

Description copied from class: SerializerWithStringManifest

Serializes the given object into an Array of Byte.

Note that the array must not be mutated by the serializer after it has been returned.
