Revert the state of the node to the current version.

The node reference will be reverted to the current version.

A deep revert will be performed.

Specified by:

See Also:

• VersionService.revert(NodeRef, Version, boolean)

revert

public void revert(NodeRef nodeRef,
 boolean deep)

Description copied from interface: VersionService

Revert the state of the node to the current version.

The node will be reverted to the current version.

Specified by:

revert in interface VersionService

Parameters:

nodeRef - the node reference

deep - true if a deep revert is to be performed, false otherwise

See Also:

• VersionService.revert(NodeRef, Version, boolean)

revert

public void revert(NodeRef nodeRef,
 Version version)

Description copied from interface: VersionService

Revert the state of the node to the specified version.

A deep revert will take place by default.

Specified by:

revert in interface VersionService

Parameters:

nodeRef - the node reference

version - the version to revert to

See Also:

• VersionService.revert(NodeRef, Version, boolean)

revert

public void revert(NodeRef nodeRef,
 Version version,
 boolean deep)

Description copied from interface: VersionService

Revert the state of the node to the specified version.

Any changes made to the node will be lost and the state of the node will reflect that of the version specified.

The version label property on the node reference will remain unchanged.

If the node is further versioned then the new version will be created at the head of the version history graph. A branch will not be created.

If a deep revert is to be performed then any child nodes that are no longer present will be deep restored (if appropriate) otherwise child associations to deleted, versioned nodes will not be restored.

Specified by:

revert in interface VersionService

Parameters:

nodeRef - the node reference

version - the version to revert to

deep - true is a deep revert is to be performed, false otherwise.

restore

public NodeRef restore(NodeRef nodeRef,
 NodeRef parentNodeRef,
 QName assocTypeQName,
 QName assocQName)

Description copied from interface: VersionService

By default a deep restore is performed.

Specified by:

restore in interface VersionService

Parameters:

nodeRef - the node reference to a node that no longer exists in the store

parentNodeRef - the new parent of the restored node

assocTypeQName - the assoc type qname

assocQName - the assoc qname

Returns:

the newly restored node reference

See Also:

• VersionService.restore(NodeRef, NodeRef, QName, QName, boolean)

restore

public NodeRef restore(NodeRef nodeRef,
 NodeRef parentNodeRef,
 QName assocTypeQName,
 QName assocQName,
 boolean deep)

Description copied from interface: VersionService

Restores a node not currently present in the store, but that has a version history.

The restored node will be at the head (most resent version).

Restoration will fail if there is no version history for the specified node id in the specified store.

If the node already exists in the store then an exception will be raised.

Once the node is restored it is reverted to the head version in the appropriate version history tree. If deep is set to true then this will be a deep revert, false otherwise.

Specified by:

restore in interface VersionService

Parameters:

nodeRef - the node reference to a node that no longer exists in the store

parentNodeRef - the new parent of the restored node

assocTypeQName - the assoc type qname

assocQName - the assoc qname

deep - true is a deep revert should be performed once the node has been restored, false otherwise

Returns:

the newly restored node reference

public void deleteVersionHistory(NodeRef nodeRef)
                          throws AspectMissingException

Description copied from interface: VersionService

This operation is permanent, all versions in the version history are deleted and cannot be retrieved.

The current version label for the node reference is reset and any subsequent versions of the node will result in a new version history being created.

Specified by:

deleteVersionHistory in interface VersionService

Parameters:

nodeRef - the node reference

Throws:

AspectMissingException - thrown if the version aspect is missing

Specified by:

deleteVersion in interface VersionService

Parameters:

nodeRef - the node reference

version - the version to delete

public void ensureVersioningEnabled(NodeRef nodeRef,
 Map<QName,Serializable> versionProperties)

Description copied from interface: VersionService

Specified by:

ensureVersioningEnabled in interface VersionService

Parameters:

nodeRef - the node reference

versionProperties - the version properties to apply if versioning isn't currently enabled for the node
