findAllChildrenCount

public Map<String,Integer> findAllChildrenCount(WikittyTransaction transaction,
                                                Wikitty w,
                                                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 but Node and subchild are not returned. This method return only one level of tree

Specified by:

findAllChildrenCount in interface WikittySearchEngine

Returns:
