Class VersionAwareMarshaller

java.lang.Object
  org.jboss.cache.marshall.AbstractMarshaller
      org.jboss.cache.marshall.VersionAwareMarshaller

All Implemented Interfaces:

Marshaller, org.jgroups.blocks.RpcDispatcher.Marshaller

public class VersionAwareMarshaller
extends AbstractMarshaller

A delegate to various other marshallers like CacheMarshaller200. This delegating marshaller adds versioning information to the stream when marshalling objects and is able to pick the appropriate marshaller to delegate to based on the versioning information when unmarshalling objects.
