Examples of AggregateOperator

    final ValueExpression<Double> substract = new Subtraction(new ValueSpecification(
        _doubleConv, 1.0), new ColumnReference(_doubleConv, 3));
    // extendedPrice*(1-discount)
    final ValueExpression<Double> product = new Multiplication(new ColumnReference(_doubleConv,
        2), substract);
    final AggregateOperator agg = new AggregateSumOperator(product, conf);


    final ColumnReference colRefL_OPartKey = new ColumnReference(_intConv, 0);
    final ColumnReference colRefS_PPartKey = new ColumnReference(_intConv, 1);
    final ColumnReference colRefL_OSupKey = new ColumnReference(_intConv, 1);
    final ColumnReference colRefS_PSupKey = new ColumnReference(_intConv, 0);

Examples of plan_runner.operators.AggregateOperator

        _queryPlan).addOperator(new ProjectOperator(new int[] { 1, 2, 3, 4 }))
        .setHashIndexes(Arrays.asList(2));

    final AggregateOperator agg = new AggregateSumOperator(new ColumnReference(_doubleConv, 2),
        conf).setGroupByColumns(Arrays.asList(1, 3));


    new EquiJoinComponent(R_N_Cjoin, S_N_P_L_Ojoin, _queryPlan).addOperator(agg);
