Examples of com.alibaba.wasp.coprocessor.FloatColumnInterpreter

com.alibaba.wasp.coprocessor.FloatColumnInterpreter
a concrete column interpreter implementation. The cell value is a Float value and its promoted data type is also a Float 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.

                        scan, Bytes.toBytes(field.getName()));
          return Bytes.toBytes(sum == null ? 0 : sum.longValue());
        }
        case FLOAT: {
          Float sum = aggregationClient
                    .sum(Bytes.toBytes(tableName), new FloatColumnInterpreter(),
                        scan, Bytes.toBytes(field.getName()));
          return Bytes.toBytes(sum == null ? 0 : sum.floatValue());
        }
        case DOUBLE: {
          Double sum = aggregationClient
