Class BytesApiMessageSerde

java.lang.Object

org.apache.kafka.server.common.serialization.BytesApiMessageSerde

public abstract class BytesApiMessageSerde
extends Object

This class provides conversion of ApiMessageAndVersion to bytes and vice versa.. This can be used as serialization protocol for any metadata records derived of ApiMessages. It internally uses AbstractApiMessageSerde for serialization/deserialization mechanism.

Implementors need to extend this class and implement apiMessageFor(short) method to return a respective ApiMessage for the given apiKey. This is required to deserialize the bytes to build the respective ApiMessage instance.
