Class VersionServiceImpl

java.lang.Object

org.fcrepo.kernel.impl.services.AbstractService

org.fcrepo.kernel.impl.services.VersionServiceImpl

All Implemented Interfaces:

VersionService

@Component
public class VersionServiceImpl
extends AbstractService
implements VersionService

This service exposes management of node versioning. Instead of invoking the JCR VersionManager methods, this provides a level of indirection that allows for special handling of features built on top of JCR such as user transactions.
