public interface ConsistencyChecker

Optional interface for Persistence Managers. Allows running consistency checks similar to the base one (see @link PersistenceManager#checkConsistency(String[], boolean, boolean) but providing a result that can be acted upon.

Beware: this interface is designed for unit tests only.

Method Detail

check

ConsistencyReport check(String[] uuids,
                      boolean recursive,
                      boolean fix,
                      String lostNFoundId)
                        throws RepositoryException

Perform a consistency check of the data. An example are non-existent nodes referenced in a child node entry. The existence of this feature and the scope of the implementation can vary in different PersistenceManager implementations.

Parameters:

uuids - list of UUIDs of nodes to be checked. if null, all nodes will be checked

recursive - if true, the tree(s) below the given node(s) will be traversed and checked as well

fix - if true, any problems found that can be repaired will be repaired. if false, no data will be modified, instead all inconsistencies will only get logged

lostNFoundId - node to which to attach orphaned nodes (or null, in which case orphaned nodes will not get moved); this node should be of a node type that allows adding arbitrary child nodes

Throws:

RepositoryException
