Method Details

add

ID add(Entity entity,
 FieldPolicy fieldPolicy)
throws DataAccessException

添加数据

若 entity 为 null, 则使用 fieldPolicy 进行纯表达式添加

Parameters:

entity - 待添加的数据 (可为 null)

fieldPolicy - 字段策略

Returns:

主键 ID (若数据没有主键, 则为 null)

Throws:

DataAccessException

add

List<ID> add(Collection<Entity> entityList,
 FieldPolicy fieldPolicy)
      throws DataAccessException

添加多条数据

由于无法对 entityList 中每个成员进行单独判断, 字段将由 fieldPolicy 统一控制

Parameters:

entityList - 待插入的数据列表 (成员可为 null)

fieldPolicy - 字段策略

Returns:

主键 ID 列表 (若数据没有主键, 则为 null 列表)

Throws:

DataAccessException

finder

Finder<Entity> finder(Query query,
 FieldPolicy fieldPolicy)

创建 Finder

Parameters:

query - 查询条件

fieldPolicy - 字段策略

Returns:

Finder

update

long update(Entity entity,
 FieldPolicy fieldPolicy,
 Query query)
     throws DataAccessException

更新数据

若 entity 为 null, 则使用 fieldPolicy 进行纯表达式更新, 此时要求 fieldPolicy 至少包含一个字段表达式

Parameters:

entity - 待更新的数据 (可为 null)

fieldPolicy - 字段策略

query - 查询条件

Returns:

更新的数据条数

Throws:

DataAccessException
