List of joinOrderToBeOptimized() Examples

Examples of joinOrderToBeOptimized()

lupos.engine.operators.index.BasicIndexScan.joinOrderToBeOptimized()
Returns whether or not the join order of the triple patterns inside this index scan operator should be optimized. This is for almost all index scan operator types true (but not for PredicateIndexScan) @return whether or not the join order of the triple patterns inside this index scan operator should be optimized

Examples of lupos.engine.operators.index.BasicIndexScan.joinOrderToBeOptimized()


    for (final OperatorIDTuple oit : this.succeedingOperators) {
      if (oit.getOperator() instanceof BasicIndexScan) {
        final BasicIndexScan indexScan = (BasicIndexScan) oit.getOperator();


        if(indexScan.joinOrderToBeOptimized()){
          final lupos.engine.operators.index.Root root;
          switch (opt) {
          default:
          case BasicIndexScan.BINARY:
            root = QueryClientCostBasedOptimizer.rearrangeJoinOrder(indexScan);
