Method Detail


Iterable<NodeId> getAllNodeIds(NodeId after,
                               int maxCount)
                               throws ItemStateException,
Get all node ids. A typical application will call this method multiple times, where 'after' is the last row read. 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.

after - the lower limit, or null for no limit.
maxCount - the maximum number of node ids to return, or 0 for no limit.
an iterator of all bundles.
ItemStateException - if an error while loading occurs.
RepositoryException - if a repository exception occurs
