Examples of MaterializedTuple

com.facebook.presto.operator.MaterializedTuple
com.facebook.presto.util.MaterializedTuple
Materialize all values from a Tuple Special handling is added for Double types for approximate comparisons

Examples of com.facebook.presto.operator.MaterializedTuple

        RecordCursor cursor = recordSet.cursor();
        while (cursor.advanceNextPosition()) {
            List<Object> values = extractValues(cursor, outputTypes);
            List<Object> keyValues = extractPositionValues(values, keyPositions);


            indexedValuesBuilder.put(new MaterializedTuple(keyValues), new MaterializedTuple(values));
        }


        return new IndexedTable(keyColumns, keyTypes, outputColumns, outputTypes, indexedValuesBuilder.build());
