This object keeps track of all of the changes within a transaction, for entities for which entity property change publishing is enabled (typically using the _DomainObject#entityChangePublishing() @DomainObject(entityChangePublishing=)_ annotation attribute.

The service is xref:refguide:applib:index/annotation/TransactionScope.adoc[TransactionScope] d and implements Spring's _TransactionSynchronization_ interface, meaning that Spring will call the _#beforeCompletion()_ callback. This service also implements _org.springframework.core.Ordered_ to ensure it isn't called last by _TransactionSynchronizationManager_ .
