Method Details

registerEntity

void registerEntity(NavigablePath navigablePath,
 EntityMappingType entityDescriptor,
 EntityKey entityKey)

Register a loading entity.

Parameters:

navigablePath - The NavigablePath relative to the SQL AST used to load the entity

entityDescriptor - The descriptor for the entity being loaded.

entityKey - The EntityKey for the entity being loaded

registerCollection

void registerCollection(NavigablePath navigablePath,
 PluralAttributeMapping collectionDescriptor,
 CollectionKey collectionKey)

Register a loading collection.

Parameters:

navigablePath - The NavigablePath relative to the SQL AST used to load the entity

collectionDescriptor - The descriptor for the collection being loaded.

collectionKey - The CollectionKey for the collection being loaded

clear

void clear()

Clears the state of the collector.

Implementation Specification:

In some cases, the collector may be cached as part of a JdbcSelect being cached (see JdbcSelect.getLoadedValuesCollector(). This method allows clearing of the internal state after execution of the JdbcSelect.

getCollectedRootEntities

List<LoadedValuesCollector.LoadedEntityRegistration> getCollectedRootEntities()

Access to all root entities loaded.

getCollectedNonRootEntities

List<LoadedValuesCollector.LoadedEntityRegistration> getCollectedNonRootEntities()

Access to all non-root entities (join fetches e.g.) loaded.

getCollectedCollections

List<LoadedValuesCollector.LoadedCollectionRegistration> getCollectedCollections()

Access to all collection loaded.
