All Implemented Interfaces:

VersionManager

public class VersionManagerImpl

extends Object

implements VersionManager

This Class implements a VersionManager.

Constructor Summary

VersionManagerImpl(PersistenceManager pMgr, NodeTypeRegistry ntReg, DelegatingObservationDispatcher obsMgr, String rootUUID, String rootParentUUID)
Creates a bew vesuion manager

Method Summary

Version	checkin(NodeImpl node) invokes the checkin() on the persistent version manager and remaps the newly created version objects.
void	close() Close this version manager.
VersionHistory	createVersionHistory(Session session, NodeState node) Creates a new version history.
List	getItemReferences(InternalVersionItem item) {@inheritDoc}
InternalVersion	getVersion(String id) Returns the version with the given id
VersionHistory	getVersionHistory(Session session, NodeState node) Returns the version history of the specified node or null if the given node doesn't (yet) have an associated version history.
InternalVersionHistory	getVersionHistory(String id) Returns the version history with the given id
VirtualItemStateProvider	getVirtualItemStateProvider() returns the virtual item state provider that exposes the internal versions as items.
boolean	hasItem(String id) checks, if the node with the given id exists
boolean	hasVersion(String id) Checks if the version with the given id exists
boolean	hasVersionHistory(String id) Checks if the version history with the given id exists
void	removeVersion(VersionHistory history, QName name) Removes the specified version from the history
void	setItemReferences(InternalVersionItem item, List references) {@inheritDoc}
boolean	setNodeReferences(NodeReferences refs)
Version	setVersionLabel(VersionHistory history, QName version, QName label, boolean move) Sets the version label to the given version. If the label is already assigned to another version, a VersionException is thrown unless move is true. If version is null, the label is removed from the respective version. In either case, the version the label was previously assigned is returned, or null of the label was not moved.

Method Detail

getVirtualItemStateProvider

public VirtualItemStateProvider getVirtualItemStateProvider()

returns the virtual item state provider that exposes the internal versions as items.
