Constructor Detail

### AbstractEntityLoader

    public AbstractEntityLoader(OuterJoinLoadable persister,
                                Type uniqueKeyType,
                                SessionFactoryImplementor factory,
                                LoadQueryInfluencers loadQueryInfluencers)

Method Detail

### load

    public Object load(Serializable id,
                       Object optionalObject,
                       SessionImplementor session)

  Load an entity instance. If `optionalObject` is supplied, load the entity state into the given (uninitialized) object.

  Specified by:
    `load` in interface `UniqueEntityLoader`

### load

    public Object load(Serializable id,
                       Object optionalObject,
                       SessionImplementor session,
                       LockOptions lockOptions)

  Load an entity instance by id. If `optionalObject` is supplied (non-`null`, the entity state is loaded into that object instance instead of instantiating a new one.

  Specified by:
    `load` in interface `UniqueEntityLoader`
  Parameters:
    `id` - The id to be loaded
    `optionalObject` - The (optional) entity instance in to which to load the state
    `session` - The session from which the request originated
    `lockOptions` - The lock options.
  Returns:
    The loaded entity

### load

    protected Object load(SessionImplementor session,
                          Object id,
                          Object optionalObject,
                          Serializable optionalId,
                          LockOptions lockOptions)

### getResultColumnOrRow

    protected Object getResultColumnOrRow(Object[] row,
                                          ResultTransformer transformer,
                                          ResultSet rs,
                                          SessionImplementor session)
                                   throws SQLException,
                                          HibernateException

  Description copied from class: `Loader`
  Get the actual object that is returned in the user-visible result list. This empty implementation merely returns its first argument. This is overridden by some subclasses.

  Overrides:
    `getResultColumnOrRow` in class `Loader`
  Throws:
    `SQLException`
    `HibernateException`

### isSingleRowLoader

    protected boolean isSingleRowLoader()

  Description copied from class: `Loader`
  Return false is this loader is a batch entity loader

  Overrides:
    `isSingleRowLoader` in class `Loader`
