      Returns:
      reference to the version store

    • isAVersion

      @Auditable boolean isAVersion(NodeRef nodeRef)

    • createVersion

      @Auditable(parameters={"nodeRef","versionProperties"}) Version createVersion(NodeRef nodeRef, Map<String,Serializable> versionProperties) throws ReservedVersionNameException, AspectMissingException
      Creates a new version based on the referenced node.

      If the node has not previously been versioned then a version history and initial version will be created.

      If the node referenced does not or can not have the version aspect applied to it then an exception will be raised.

      The version properties are stored as version meta-data against the newly created version.

    • getCurrentVersion

      @Auditable(parameters="nodeRef") Version getCurrentVersion(NodeRef nodeRef)
      Gets the version object for the current version of the node reference passed.

      Returns null if the node is not versionable or has not been versioned.

      Parameters:
      nodeRef - the node reference of the 'live' node
      Returns:

    • revert

      @Auditable(parameters="nodeRef") void revert(NodeRef nodeRef)
      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.

      Parameters:
      nodeRef - the node reference
      See Also:

    • revert

      @Auditable(parameters={"nodeRef","deep"}) void revert(NodeRef nodeRef, boolean deep)
      Revert the state of the node to the current version.

      The node will be reverted to the current version.

      Parameters:
      nodeRef - the node reference
      deep - true if a deep revert is to be performed, false otherwise
      See Also:

    • revert

      @Auditable(parameters={"nodeRef","version"}) void revert(NodeRef nodeRef, Version version)
      Revert the state of the node to the specified version.

      A deep revert will take place by default.

      Parameters:
      nodeRef - the node reference
      version - the version to revert to
      See Also:

    • revert

      @Auditable(parameters={"nodeRef","version","deep"}) void revert(NodeRef nodeRef, Version version, boolean deep)
      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.

      Parameters:
      nodeRef - the node reference
      version - the version to revert to
      deep - true is a deep revert is to be performed, false otherwise.

    • restore

      @Auditable(parameters={"nodeRef","parentNodeRef","assocTypeQName","assocQName"}) NodeRef restore(NodeRef nodeRef, NodeRef parentNodeRef, QName assocTypeQName, QName assocQName)
      By default a deep restore is performed.
      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:

    • restore

      @Auditable(parameters={"nodeRef","parentNodeRef","assocTypeQName","assocQName","deep"}) NodeRef restore(NodeRef nodeRef, NodeRef parentNodeRef, QName assocTypeQName, QName assocQName, boolean deep)
      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.

      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

    • deleteVersionHistory

      @Auditable(parameters="nodeRef") void deleteVersionHistory(NodeRef nodeRef) throws AspectMissingException
      Delete the version history associated with a node reference.

      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.

      Parameters:
      nodeRef - the node reference
      Throws:
      AspectMissingException - thrown if the version aspect is missing

    • deleteVersion

      @Auditable(parameters={"nodeRef","version"}) void deleteVersion(NodeRef nodeRef, Version version)
      Delete a specific version associated with a node reference.

      This operation is permanent, the specific version in the version history is deleted and cannot be retrieved.

      If this is the last version, then 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.

      Parameters:
      nodeRef - the node reference
      version - the version to delete

    • ensureVersioningEnabled

      @Auditable(parameters="nodeRef") void ensureVersioningEnabled(NodeRef nodeRef, Map<QName,Serializable> versionProperties)
      Ensures that a node has the versionable aspect applied to it, and has at least an initial entry in the version store. If any of these requirements are missing, then they will be fixed.
      Parameters:
      nodeRef - the node reference
      versionProperties - the version properties to apply if versioning isn't currently enabled for the node

    • registerVersionLabelPolicy

      void registerVersionLabelPolicy(QName typeQName, VersionServicePolicies.CalculateVersionLabelPolicy policy)
      Register a version label policy
      Parameters:
      typeQName - the QName of the type to register
      policy - the policy to register for the specified type
