public SqlFieldMacro(MappingField field,
                     String str)

Method Detail

setOperatingObject

public Pojo setOperatingObject(Object obj)

Description copied from interface: Pojo

设置一个 POJO 正在操作的对象

Specified by:

setOperatingObject in interface Pojo

Overrides:

setOperatingObject in class NutPojo

Parameters:

obj - 正在操作的对象

onAfter

public void onAfter(Connection conn,
                    ResultSet rs,
                    Statement stmt)
             throws SQLException

Description copied from interface: DaoStatement

语句执行完毕的后续操作

这个接口函数你基本不会直接使用的

Specified by:

onAfter in interface DaoStatement

Overrides:

onAfter in class NutPojo

Parameters:

conn - 当前执行语句的连接

rs - 当前语句执行的结果集

stmt - TODO

Throws:

SQLException - 回调函数抛出的异常

getSqlType

public SqlType getSqlType()

Specified by:

getSqlType in interface DaoStatement

Overrides:

getSqlType in class NutStatement

Returns:

返回执行的语句的类型

getAdaptors

public ValueAdaptor[] getAdaptors()

Description copied from interface: DaoStatement

为本语句每一个参数提供一个适配器

Specified by:

getAdaptors in interface DaoStatement

Overrides:

getAdaptors in class NutPojo

Returns:

JDBC 缓冲语句的参数适配器

getParamMatrix

public Object[][] getParamMatrix()

Description copied from interface: DaoStatement

用一个矩阵描述语句的参数表。
这个参数矩阵将同 getAdaptors() 的返回组合使用

矩阵的每一行相当于执行一条语句

参数表的下标意义为： Object[行][列]

Specified by:

getParamMatrix in interface DaoStatement

Overrides:

getParamMatrix in class NutPojo

Returns:

语句参数表

toPreparedStatement

public String toPreparedStatement()

Description copied from interface: DaoStatement

将 Dao 语句转换为 JDBC SQL 缓冲语句

Specified by:

toPreparedStatement in interface DaoStatement

Overrides:

toPreparedStatement in class NutPojo

Returns:

JDBC SQL 缓冲语句

duplicate

public Pojo duplicate()

Description copied from interface: Pojo

复制一份自己的实例

Specified by:

duplicate in interface Pojo

Overrides:

duplicate in class NutPojo

Returns:

一份新的自己

prepareVarParam

protected void prepareVarParam(Sql sql)

getFieldVale

protected Object getFieldVale(String name,
                              Object obj)
