Examples of org.infinispan.transaction.xa.GlobalTransaction

org.infinispan.transaction.xa.GlobalTransaction
Uniquely identifies a transaction that spans all JVMs in a cluster. This is used when replicating all modifications in a transaction; the PREPARE and COMMIT (or ROLLBACK) messages have to have a unique identifier to associate the changes with
. GlobalTransaction should be instantiated thorough {@link TransactionFactory} class,as their type depends on the runtime configuration. @author Bela Ban Apr 12, 2003 @author Manik Surtani (manik@jboss.org) @author Mircea.Markus@jboss.com @since 4.0
