The Marshaller interface extends RpcDispatcher.Marshaller from JGroups. This interface has two main implementations - a delegating VersionAwareMarshaller and a concrete CacheMarshaller200 .

The marshaller can be obtained by calling CacheSPI.getMarshaller() , and defaults to the VersionAwareMarshaller . Users may also write their own marshallers by implementing the Marshaller interface and adding it to their configuration, by using the MarshallerClass configuration attribute.
