Method Detail

clear

void clear(WikittyTransaction transaction)

Remove all data in index

store

void store(WikittyTransaction transaction,
           Collection<Wikitty> wikitties)

Store wikitty in storage Tree are reindexed if necessary.

delete

void delete(WikittyTransaction transaction,
            Collection<String> idList)
            throws WikittyException

Delete all object with idList argument. If id is not valid or don't exist. Tree are reindexed if necessary.

Parameters:

idList - list of ids to delete

Throws:

WikittyException

findAllByCriteria

PagedResult<String> findAllByCriteria(WikittyTransaction transaction,
                                      Criteria criteria)

findNodeCount

Integer findNodeCount(WikittyTransaction transaction,
                      Wikitty w,
                      Criteria filter)

Find count of child for a node

Parameters:

w -

Returns:

findAllChildrenCount

Map<String,Integer> findAllChildrenCount(WikittyTransaction transaction,
                                         Wikitty w,
                                         Criteria filter)

Find all children ids with attachment count for a node wikitty. If same attachment found many time in subtree this attachment is count only once. If we have:

• w Node (4)
  • child1 (3)
  • child2 (4)
  • child3 (2)
    • subchild1 (1)
    • subchild2 (5)
  • child4 (3)
  • child5 (7)

return count for: child1(3), child2(4), child3(8), child4(3), child5(7) and for the child3 count we have count of subchild1 and subchild2 in but Node and subchild are not returned. This method return only one level of tree

Parameters:

w -

Returns:
