Class JBossMarshaller

          org.infinispan.marshall.jboss.JBossMarshaller

All Implemented Interfaces:

Marshaller, StreamingMarshaller

public class JBossMarshaller
extends GenericJBossMarshaller
implements StreamingMarshaller

A specialized form of the GenericJBossMarshaller, making use of a custom object table for types internal to Infinispan.

The reason why this is implemented specially in Infinispan rather than resorting to Java serialization or even the more efficient JBoss serialization is that a lot of efficiency can be gained when a majority of the serialization that occurs has to do with a small set of known types such as GlobalTransaction or ReplicableCommand, and class type information can be replaced with simple magic numbers.

Unknown types (typically user data) falls back to JBoss serialization.
