方法详细资料

queryIds

List<I> queryIds(Q query)

queryColumns

<V> List<V> queryColumns(Q query,
                         Class<V> clazz,
                         String... columns)

create

void create(E e)

update

int update(E e)

save

default E save(E e)

isNewEntity

default boolean isNewEntity(E e)

patch

int patch(E e)

create

int create(Iterable<E> entities,
           String... columns)

执行INSERT INTO [TABLE] (col1, col2) VALUES (?), (?)

1. 会清空全部缓存
2. 不会按id清理缓存
3. 不会执行EntityAspect.afterCreate(Object)

参数:

entities - entities to insert

columns - update columns on duplicate

返回:

amount of updated entities

batchInsert

@Deprecated
default int batchInsert(Iterable<E> entities,
                                    String... columns)

已过时。 use create(Iterable, String[])

patch

int patch(E e,
          Q q)

执行UPDATE [TABLE] SET ... WHERE ...

1. 会清空全部缓存
2. 不会按id清理缓存
3. 不会执行EntityAspect.afterUpdate(Object, Object)

参数:

e - entity object

q - query object

返回:

amount of updated entities

delete

int delete(Q q)

执行DELETE FORM [TABLE] WHERE ...

1. 会清空全部缓存
2. 不会按id清理缓存
3. 不会执行EntityAspect.afterDelete(Object)

参数:

q - query object

返回:

amount of updated entities

get

E get(IdWrapper<I> w)

Get origin entity from sharding table

参数:

w - an entity just contains id and information of sharding table

返回:

origin entity

fetch

E fetch(IdWrapper<I> w)

force to get a new entity object from database

参数:

w - entity id

返回:

a new entity object

delete

E delete(IdWrapper<I> w)

Delete entity from sharding table

参数:

w - an entity just contains id and information of sharding table

返回:

origin entity
