java.lang.Object java.lang.Enum<FlushModeType> javax.persistence.FlushModeType
public enum FlushModeType
Flush mode setting.
When queries are executed within a transaction, if
FlushModeType.AUTO
is set on the Query
object, or if the flush mode setting for the persistence context
is AUTO
(the default) and a flush mode setting has
not been specified for the Query
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. If FlushModeType.COMMIT
is set, the effect
of updates made to entities in the persistence context upon
queries is unspecified.
If there is no transaction active, the persistence provider must not flush to the database.
