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:

AbstractColumFunction, AllColumn, AnonymousFunction, Column, ColumnFunctionDecorator, Count, Distinct, JsonExtract, JsonUnquote, Length, Max, Md5, NumberColumn, SubString, Sum, Upper

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
