import org.springframework.core.Ordered;

Simple TransactionSynchronization adapter containing empty method implementations, for easier overriding of single methods. 
Also implements the Ordered interface to enable the execution order of synchronizations to be controlled declaratively. The default order is Ordered.LOWEST_PRECEDENCE, indicating late execution; return a lower value for earlier execution.
