Method Detail

clear

public void clear(WikittyTransaction transaction)

Description copied from interface: WikittySearchEngine

Remove all data in index

Specified by:

clear in interface WikittySearchEngine

store

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

Description copied from interface: WikittySearchEngine

Store wikitty in storage Tree are reindexed if necessary.

Specified by:

store in interface WikittySearchEngine

force - if true, force indexation of wikitty, otherwize only dirty or new wikitties are indexed

delete

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

Description copied from interface: WikittySearchEngine

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

Specified by:

delete in interface WikittySearchEngine

idList - list of ids to delete

Throws:

WikittyException

findAllByQuery

public WikittyQueryResult<Map<String,Object>> findAllByQuery(WikittyTransaction transaction,
                                                    WikittyQuery query)

Description copied from interface: WikittySearchEngine

Find all values that satisfy queries constraint. Values is Wikitty's id if there is no Select condition, otherwize is String that represent field value and can be String representation of Wikitty, Date, Boolean, Numeric, Binary, String. Or TODO (map? array?)

Specified by:

findAllByQuery in interface WikittySearchEngine

Returns:

id of wikitties

findAllChildrenCount

public WikittyQueryResultTreeNode<String> findAllChildrenCount(WikittyTransaction transaction,
                                                      String wikittyId,
                                                      int depth,
                                                      boolean count,
                                                      WikittyQuery filter)

Description copied from interface: WikittySearchEngine

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 Node and subchild are returned according to depth

Specified by:

findAllChildrenCount in interface WikittySearchEngine

wikittyId - root node to begin

depth - depth of node returned, -1 to retrieve all child level

count - if true return count of attachment

filter - filter on attachment count

Returns:

Tree start with wikittyId as root

findAllByCriteria

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

Specified by:

findAllByCriteria in interface WikittySearchEngine

findAllChildrenCount

public TreeNodeResult<String> findAllChildrenCount(WikittyTransaction transaction,
                                          String wikittyId,
                                          int depth,
                                          boolean count,
                                          Criteria filter)

Description copied from interface: WikittySearchEngine

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 Node and subchild are returned according to depth

Specified by:

findAllChildrenCount in interface WikittySearchEngine

wikittyId - root node to begin

depth - depth of node returned, -1 to retrieve all child level

count - if true return count of attachment
