determineFetchStyleByProfile

public static FetchStyle determineFetchStyleByProfile(LoadQueryInfluencers loadQueryInfluencers,
                                                      EntityPersister persister,
                                                      PropertyPath path,
                                                      int propertyNumber)

Determine the fetch-style (if one) explicitly set for this association via fetch profiles.

Note that currently fetch profiles only allow specifying join fetching, so this method currently returns either (a) FetchStyle.JOIN or (b) null

参数:

loadQueryInfluencers -

persister -

path -

propertyNumber -

返回:

determineFetchStyleByMetadata

public static FetchStyle determineFetchStyleByMetadata(FetchMode mappingFetchMode,
                                                       AssociationType type,
                                                       SessionFactoryImplementor sessionFactory)

参数:

mappingFetchMode - The mapping defined fetch mode

type - The association type

sessionFactory - The session factory

返回:

the fetch style

determineFetchTiming

public static FetchTiming determineFetchTiming(FetchStyle style,
                                               AssociationType type,
                                               SessionFactoryImplementor sessionFactory)

isJoinFetched

public static boolean isJoinFetched(FetchStrategy fetchStrategy)
