Modifier and Type | Method and Description |
---|---|
protected String |
applyLocks(String sql,
QueryParameters parameters,
Dialect dialect,
List<AfterLoadAction> afterLoadActions)
Append FOR UPDATE OF clause, if necessary.
|
protected void |
autoDiscoverTypes(ResultSet rs) |
protected CollectionAliases[] |
getCollectionAliases() |
protected int[] |
getCollectionOwners()
Get the index of the entity that owns the collection, or -1
if there is no owner in the query results (ie.
|
protected CollectionPersister[] |
getCollectionPersisters()
An (optional) persister for a collection to be initialized; only
collection loaders return a non-null value
|
protected EntityAliases[] |
getEntityAliases()
Get the result set descriptor
|
protected Loadable[] |
getEntityPersisters()
An array of persisters of entity classes contained in each row of results;
implemented by all subclasses
|
protected LockMode[] |
getLockModes(LockOptions lockOptions)
What lock options does this load entities with?
|
int[] |
getNamedParameterLocs(String name) |
protected int[] |
getOwners()
An array of indexes of the entity that owns a one-to-one association
to the entity at the given index (-1 if there is no "owner").
|
protected String |
getQueryIdentifier()
Identifies the query for statistics reporting, if null,
no statistics will be reported
|
Set |
getQuerySpaces() |
protected Object |
getResultColumnOrRow(Object[] row,
ResultTransformer transformer,
ResultSet rs,
SessionImplementor session)
Get the actual object that is returned in the user-visible result list.
|
protected List |
getResultList(List results,
ResultTransformer resultTransformer) |
protected Object[] |
getResultRow(Object[] row,
ResultSet rs,
SessionImplementor session) |
protected String[] |
getResultRowAliases()
Returns the aliases that corresponding to a result row.
|
String |
getSQLString()
The SQL query string to be called; implemented by all subclasses
|

QueryParameters queryParameters) |
protected void |
putResultInQueryCache(SessionImplementor session,
QueryParameters queryParameters,
Type[] resultTypes,
QueryCache queryCache,
QueryKey key,
List result)
resultTypes can be overridden by autoDiscoverTypes(ResultSet) ,
*after* list(SessionImplementor, QueryParameters) has already been called. |

resolveResultTransformer(ResultTransformer resultTransformer)
Determine the actual ResultTransformer that will be used to
transform query results.

resultTypes
can be overridden by autoDiscoverTypes(ResultSet)
,
*after* list(SessionImplementor, QueryParameters)
has already been called. It's a bit of a
chicken-and-the-egg issue since autoDiscoverTypes(ResultSet)
needs the ResultSet
.
As a hacky workaround, override
putResultInQueryCache(SessionImplementor, QueryParameters, Type[], QueryCache, QueryKey, List)
here
and provide the resultTypes
.
