Examples of com.alibaba.wasp.coprocessor.IntegerColumnInterpreter

com.alibaba.wasp.coprocessor.IntegerColumnInterpreter
a concrete column interpreter implementation. The cell value is a Integer value and its promoted data type is also a Integer value. For computing aggregation function, this class is used to find the datatype of the cell value. Client is supposed to instantiate it and passed along as a parameter. See TestAggregateProtocol methods for its sample usage. Its methods handle null arguments gracefully.


    private byte[] getSumValue(String tableName, Field field, Scan scan) throws Throwable {
      switch (field.getType()) {
        case INT32: {
          Integer sum = aggregationClient
                    .sum(Bytes.toBytes(tableName), new IntegerColumnInterpreter(),
                        scan, Bytes.toBytes(field.getName()));
          return Bytes.toBytes(sum == null ? 0 : sum.intValue());
        }
        case INT64: {
          Long sum = aggregationClient
