Constructor Detail

EntityLoadQueryDetails

protected EntityLoadQueryDetails(LoadPlan loadPlan,
                      String[] keyColumnNames,
                      AliasResolutionContextImpl aliasResolutionContext,
                      EntityReturn rootReturn,
                      QueryBuildingParameters buildingParameters,
                      SessionFactoryImplementor factory)

Constructs a EntityLoadQueryDetails object from the given inputs.

Parameters:

loadPlan - The load plan

keyColumnNames - The columns to load the entity by (the PK columns or some other unique set of columns)

buildingParameters - And influencers that would affect the generated SQL (mostly we are concerned with those that add additional joins here)

factory - The SessionFactory
