/**
 * Flush mode setting.
 *
 * 

When queries are executed within a transaction, if * FlushModeType.AUTO is set on the {@link 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 {@link 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. * * @since Java Persistence 1.0 */ public enum FlushModeType { /** Flushing must occur only at transaction commit */ COMMIT, /** (Default) Flushing to occur at query execution */ AUTO }
