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. 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 bundles.

Throws:

ItemStateException - if an error while loading occurs.

RepositoryException - if a repository exception occurs
