||
| 7 | * When queries are executed within a transaction, if FlushModeType.AUTO is set on the Query object, |
||
| 8 | * or if the flush mode setting for the persistence context is AUTO (the default) and a flush mode |
||
| 9 | * setting has not been specified for the Query object, the persistence provider is responsible for |
||
| 10 | * ensuring that all updates to the state of all entities in the persistence context which could |
||
| 11 | * potentially affect the result of the query are visible to the processing of the query. |
||
| 12 | * The persistence provider implementation may achieve this by flushing those entities to the database |
||
| 13 | * or by some other means. If FlushModeType.COMMIT is set, the effect of updates made to entities in the |
||
| 14 | * persistence context upon queries is unspecified. |
||
| 15 | * |
||
| 16 | * If there is no transaction active, the persistence provider must not flush to the database. |
