public interface IterablePersistenceManager
extends PersistenceManager

The iterable persistence manager can return the list of NodeIds and NodeInfos that are stored. Possible applications are backup, migration (copying a workspace or repository), data store garbage collection, and consistency checking.

Method Detail

getAllNodeIds

List<NodeId> getAllNodeIds(NodeId after,
                           int maxCount)
                    throws ItemStateException,
                           RepositoryException

Get all node ids. A typical application will call this method multiple times, where 'after' is the last row read previously. The maxCount parameter defines the maximum number of node ids returned, 0 meaning no limit. The order of the node ids is specific for the given persistent manager. Items that are added concurrently may not be included.

Parameters:

after - the lower limit, or null for no limit.

maxCount - the maximum number of node ids to return, or 0 for no limit.

Returns:

a list of all node ids.

Throws:

ItemStateException - if an error while loading occurs.

RepositoryException - if a repository exception occurs.

getAllNodeInfos

Map<NodeId,NodeInfo> getAllNodeInfos(NodeId after,
                                     int maxCount)
                              throws ItemStateException,
                                     RepositoryException

Get all NodeInfos. A typical application will call this method multiple time, where 'after' is the last row read previously. The maxCount parameter defines the maximum number of node ids returned, 0 meaning no limit. The order of the node ids is specific for the given persistence manager. Items that are added concurrently may not be included.

Parameters:

after - the lower limit, or null for no limit.

maxCount - the maximum number of node infos to return, or 0 for no limit.

Returns:

a list of all node infos.

Throws:

ItemStateException - if an error while loading occurs.

RepositoryException - if a repository exception occurs.
