public enumFlushModeTypeextendsEnum<FlushModeType>
When queries are executed within a transaction, ifFlushModeType.AUTO is set on theQuery orTypedQuery object, or if the flush mode setting for the persistence context isAUTO (the default) and a flush mode setting has not been specified for theQuery orTypedQuery object, the persistence provider is responsible for ensuring that all updates to the state of all entities in the persistence context which could potentially affect the result of the query are visible to the processing of the query. The persistence provider implementation may achieve this by flushing those entities to the database or by some other means.
IfFlushModeType.COMMIT is set, the effect of updates made to entities in the persistence context upon queries is unspecified.
If there is no transaction active or the persistence context is not joined to the current transaction, the persistence provider must not flush to the database.
