Examples of MemoryIndexScan

lupos.engine.operators.index.memoryindex.MemoryIndexScan
Instances of this class are used to process queries by using a special index structure for enhancement.
The index structure has to be initialized previously. It is stored in a static way so new instantiations of this class to not yield a change in the original index structure.

  protected BasicIndexScan getIndex(final LeafNodePlan plan,
      final BasicIndexScan indexScan,
      final Collection<Variable> sortCriterium,
      final Map<Variable, Literal> minima,
      final Map<Variable, Literal> maxima) {
    final BasicIndexScan index1 = new MemoryIndexScan((OperatorIDTuple) null, plan.getTriplePatterns(), indexScan.getGraphConstraint(), indexScan.getRoot());
    return index1;
