Examples of org.jrdf.collection.IteratorTrackingCollectionFactory

org.jrdf.collection.IteratorTrackingCollectionFactory
An iterator tracking collection factory. This is used when creating/removing iterators relies on some underlying resources.

        MoleculeStructureIndex<Long>[] structureIndexes = createMoleculeStructureIndexes(graphNumber);
        ReadableIndex<Long> readIndex = new ReadableIndexImpl(structureIndexes);
        WritableIndex<Long> writeIndex = new WritableIndexImpl(structureIndexes);
        LongIndex[] longIndexes = new LongIndex[]{new LongIndexAdapter(structureIndexes[0]),
            new LongIndexAdapter(structureIndexes[1]), new LongIndexAdapter(structureIndexes[2])};
        IteratorTrackingCollectionFactory collectionFactory = base.createCollectionFactory(graphNumber);
        Graph graph = new OrderedGraphFactoryImpl(longIndexes, nodePool, collectionFactory).getGraph();
        final long curMaxMoleculeId = readIndex.getMaxMoleculeId();
        Localizer localizer = new LocalizerImpl(nodePool, STRING_MAPPER);
        MoleculeLocalizer moleculeLocalizer = new MoleculeLocalizerImpl(localizer, curMaxMoleculeId);
        return new MoleculeGraphImpl(writeIndex, readIndex, moleculeLocalizer, graph, nodePool);
