Throws:

HibernateException

load

@Deprecated
public Object load(Serializable id,
                     Object optionalObject,
                     SessionImplementor session)
            throws HibernateException

Deprecated.

Description copied from interface: UniqueEntityLoader

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

Specified by:

load in interface UniqueEntityLoader

Throws:

HibernateException

load

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

Description copied from interface: UniqueEntityLoader

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

extractEntityResult

protected Object extractEntityResult(List results)

protected int[] getNamedParameterLocs(String name)

Specified by:

getNamedParameterLocs in class AbstractLoadPlanBasedLoader

autoDiscoverTypes

protected void autoDiscoverTypes(ResultSet rs)

Specified by:

autoDiscoverTypes in class AbstractLoadPlanBasedLoader
