/**
 * Flush mode setting.
 *
 * 

When queries are executed within a transaction, if * FlushModeType.AUTO is set on the {@link * javax.persistence.Query Query} or {@link javax.persistence.TypedQuery * TypedQuery} 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 or * TypedQuery 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 or the persistence context is not * joined to the current transaction, the persistence provider must not flush * to the database. * * @since Java Persistence 1.0 */ public enum FlushModeType { /** Flushing to occur at transaction commit. The provider may flush * at other times, but is not required to. */ COMMIT, /** (Default) Flushing to occur at query execution. */ AUTO }
