Class ProtobufSerializerHook<T extends>

Type Parameters:
T - the Protocol Buffers GeneratedMessageV3 type handled by this SerializerHook.
All Implemented Interfaces:

public abstract class ProtobufSerializerHook<T extends> extends Object implements SerializerHook<T>
Simplifies using the Hazelcast Serializer Hook mechanism to register a Google Protocol Buffers serializer with the Hazelcast Jet cluster. The serialized class can then be used in Hazelcast data structures and Jet jobs.

To use it, create a JAR containing the serializer hook class and META-INF/services/com.hazelcast.SerializerHook, a plain-text file containing its fully qualified name. Visit Jet's Serialization Guide for more details.
