<T> T |
getReference(Class<T> type,
Serializable id)
Get a reference to the entity with the specified type and id from the
datastore.
|
<T> T[] |
getReferences(Class<T> type,
Serializable... ids)
Get a reference to the entities of the specified type with the given ids
from the datastore.
|
boolean |
isAttached(Object entity)
Returns
true if the object is connected to the current
Hibernate session. |
void |
refresh(Object... entities)
Refresh the content of the given entity from the current datastore state.
|
void |
remove(Object... entities)
Remove all of the specified entities from the datastore.
|
boolean |
remove(Object entity)
Remove the specified entity from the datastore.

boolean |
removeById(Class<?> type,
Serializable id)

removeByIds(Class<?> type,
Serializable... ids)
Remove all the entities of the given type from the datastore that have
one of these ids.
|
boolean[] |
save(Object... entities)
For each entity, if the id of the entity is null or zero, add it to the
datastore and assign it an id; otherwise, update the corresponding entity
in the datastore with the properties of this entity.
|
boolean |
save(Object entity)
If the id of the entity is null or zero, add it to the datastore and
assign it an id; otherwise, update the corresponding entity in the
datastore with the properties of this entity.

List |
search(ISearch search)
Search for objects given the search parameters in the specified
ISearch object. |
SearchResult |
searchAndCount(ISearch search)
Returns a
SearchResult object that includes both the list of
results like search() and the total length like
count(). |

GeneralDAOGet a reference to the entity with the specified type and id from the datastore.
This does not require a call to the datastore and does not populate any of the entity's values. Values may be fetched lazily at a later time. This increases performance if a another entity is being saved that should reference this entity but the values of this entity are not needed.
getReference in interface GeneralDAOpublic <T> T[] getReferences(Class<T> type, Serializable... ids)
GeneralDAOGet a reference to the entities of the specified type with the given ids from the datastore. An array of entities is returned that matches the same order of the ids listed in the call.
This does not require a call to the datastore and does not populate any of the entities' values. Values may be fetched lazily at a later time. This increases performance if a another entity is being saved that should reference these entities but the values of these entities are not needed.

GeneralDAOIf the id of the entity is null or zero, add it to the datastore and assign it an id; otherwise, update the corresponding entity in the datastore with the properties of this entity. In either case the entity passed to this method will be attached to the session.
If an entity to update is already attached to the session, this method will have no effect. If an entity to update has the same id as another instance already attached to the session, an error will be thrown.
