Method Detail

getAssociatedEntitiesFromIndex

List getAssociatedEntitiesFromIndex(Class owningClazz,
                                  Object entityId,
                                  Class<?> childClass,
                                  Client childClient)

Retrieves associated entities from secondary index. There are two alternatives here: 1. Via running Lucene query into Lucene powered secondary index. 2. Searching into a secondary index by custom secondary index class provided by user.

See Also:

PersistenceProperties.KUNDERA_INDEX_HOME_DIR, TODO: Which secondary index to use should be transparent. All we should bother about is indexer.index(), indexer.search() etc.

populateRelationForM2M
