LoadQueryJoinAndFetchProcessor

public LoadQueryJoinAndFetchProcessor(AliasResolutionContextImpl mutableAliasResolutionContext,
                                      LoadQueryInfluencers queryInfluencers,
                                      SessionFactoryImplementor factory)

Instantiates a LoadQueryJoinAndFetchProcessor with the given information

Parameters:

mutableAliasResolutionContext -

queryInfluencers -

factory -

LoadQueryJoinAndFetchProcessor

public LoadQueryJoinAndFetchProcessor(LoadQueryJoinAndFetchProcessor initialLoadQueryJoinAndFetchProcessor,
                                      LoadQueryInfluencers queryInfluencers)

Instantiates a LoadQueryJoinAndFetchProcessor from an initial object and new query influencers. Aliases are considered already contributed to the initial objects alias resolution context and won't be added again.

Parameters:

initialLoadQueryJoinAndFetchProcessor - The initial object to be copied

queryInfluencers - The new query influencers
