Examples of DoubleColumnInterpreter

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