### Question:
ImportDb { protected boolean matchesClassification(Node n, List<RankedName> classification) { Iterator<RankedName> clIter = classification.listIterator(); Iterator<Node> nodeIter = Traversals.PARENTS.traverse(n).nodes().iterator(); while (clIter.hasNext()) { if (!nodeIter.hasNext()) { return false; } RankedName rn1 = clIter.next(); RankedName rn2 = dao.readRankedName(nodeIter.next()); if (rn1.rank != rn2.rank || !rn1.name.equals(rn2.name)) { return false; } } return !nodeIter.hasNext(); } ImportDb(UUID datasetKey, UsageDao dao); UUID getDatasetKey();  }### Answer:
