Method Detail

getVirtualItemStateProvider

VirtualItemStateProvider getVirtualItemStateProvider()

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

Returns:

the virtual item state provider.

getVersionHistory

VersionHistoryInfo getVersionHistory(Session session,
                                     NodeState vNode,

                              throws RepositoryException

Returns information about the version history of the specified node. If the given node does not already have an associated version history, then an empty history is automatically created. This method should only be called by code that already knows that the specified node is versionable.

Parameters:

session - workspace session

vNode - node whose version history should be returned

copiedFrom - the node id for the jcr:copiedFrom property use for copied nodes

Returns:

identifiers of the version history and root version nodes

Throws:

RepositoryException - if an error occurs

checkin

                        Calendar created)
                 throws RepositoryException

invokes the checkin() on the persistent version manager and remaps the newly created version objects.

Parameters:

session - session that invokes the checkin

node - node to checkin

created - create time of the new version, or null for the current time

Returns:

the newly created version

Throws:

RepositoryException - if an error occurs

canCheckout

NodeId canCheckout(NodeStateEx state,
                   NodeId activityId)
            throws RepositoryException

invokes the checkout() on the persistent version manager.

Parameters:

state - node to checkout

activityId - node id if the current activity

Returns:

the base version id

Throws:

RepositoryException - if an error occurs

removeVersion

void removeVersion(Session session,
                   InternalVersionHistory history,
                   Name versionName)
            throws RepositoryException

Removes the specified version from the given version history.

Parameters:

session - the session that performs the remove

history - version history to remove the version from

versionName - name of the version

Throws:

RepositoryException - if an error occurs

removeVersionHistory

void removeVersionHistory(Session session,
                          InternalVersionHistory history)
                   throws RepositoryException

Removes the specified version history from storage.

Parameters:

session - the session that performs the remove

history - the version history to remove

Throws:

RepositoryException - if an error occurs

setVersionLabel

InternalVersion setVersionLabel(Session session,
                                InternalVersionHistory history,
                                Name version,
                                Name label,
                                boolean move)
                         throws RepositoryException

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.

Parameters:

session - the session that performs the operation

history - version history

version - name of the version

label - new label

move - if true label will be moved

Returns:

the version that had the label or null

id - id of the node to retrieve the version history for

Returns:

the version history

Throws:

RepositoryException - if an error occurs or the history does not exit

getVersion

InternalVersion getVersion(NodeId id)
