org.hibernate.loader.plan.exec.internal.AbstractLoadQueryDetails

org.hibernate.loader.plan.exec.internal.EntityLoadQueryDetails

所有已实现的接口:

LoadQueryDetails

public class EntityLoadQueryDetails
extends AbstractLoadQueryDetails

Handles interpreting a LoadPlan (for loading of an entity) by:

• generating the SQL query to perform
• creating the readers needed to read the results from the SQL's ResultSet

EntityLoadQueryDetails

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

Constructs a EntityLoadQueryDetails object from the given inputs.

参数:

loadPlan - The load plan

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

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

factory - The SessionFactory

EntityLoadQueryDetails

protected EntityLoadQueryDetails(EntityLoadQueryDetails initialEntityLoadQueryDetails,
                                 QueryBuildingParameters buildingParameters)
