Class RepositoryMemento

java.lang.Object
  org.openrdf.repository.memento.RepositoryMemento

All Implemented Interfaces:

RepositoryConnectionListener

public class RepositoryMemento
extends Object
implements RepositoryConnectionListener

Tracks changes to a RepositoryConnection and allows those changes to be reversed. There is a performance hit when this object is attached to a RepositoryConnection. This object depends on NotifyingRepository to be on the stack. If the repository does not support or have enabled read uncommitted, the StatementRealizerRepository must be a delegate of NotifyingRepository.
