com.mybatisflex.core.query.QueryColumn

所有已实现的接口:

CloneSupport<QueryColumn>, Serializable, Cloneable

直接已知子类:

ArithmeticQueryColumn, CaseQueryColumn, CaseSearchQueryColumn, DistinctQueryColumn, FunctionQueryColumn, IfFunctionQueryColumn, SelectQueryColumn, StringFunctionQueryColumn, StringQueryColumn

public class QueryColumn
extends Object
implements CloneSupport<QueryColumn>
