Class MessagingService.CallbackDeterminedSerializer

java.lang.Object

org.apache.cassandra.net.MessagingService.CallbackDeterminedSerializer

All Implemented Interfaces:

IVersionedSerializer<java.lang.Object>

Enclosing class:

MessagingService

public static class MessagingService.CallbackDeterminedSerializer
extends java.lang.Object
implements IVersionedSerializer<java.lang.Object>

a placeholder class that means "deserialize using the callback." We can't implement this without special-case code in InboundTcpConnection because there is no way to pass the message id to IVersionedSerializer.
