接口 ColumFunction

所有已知子接口:

AggregateFunction, ConversionFunction, DatetimeFunction, JsonFunction, LogicalFunction, NumberFunction, ScalarFunction, StringFunction, WindowsFunction

所有已知实现类:

Abs, AbstractColumFunction, AllColumn, AnonymousFunction, AsBinary, AsText, Avg, CaseWhen, Ceiling, Column, ColumnFunctionDecorator, Contains, Count, DateFormat, DenseRank, Distance, DistanceSphere, Distinct, Floor, JsonExtract, JsonUnquote, Latitude, Length, Longitude, Max, Md5, Min, Mod, Now, NumberColumn, Rank, Round, RowNumber, SRID, StdDev, SubString, Sum, Truncate, Upper, Variance

public interface ColumFunction

一般情况下实现者不能直接实现该类，需要先继承AbstractColumFunction，因为AbstractColumFunction附带列运算
