Method Summary

DirectoryProvider<?>	getDirectoryProviderForAddition(Class<?> entity, Serializable id, String idInString, Document document) return the DirectoryProvider where the given entity will be indexed
DirectoryProvider<?>[]	getDirectoryProvidersForAllShards() Ask for all shards (eg to query or optimize)
DirectoryProvider<?>[]	getDirectoryProvidersForDeletion(Class<?> entity, Serializable id, String idInString) return the DirectoryProvider(s) where the given entity is stored and where the deletion operation needs to be applied id and idInString can be null.
void	initialize(Properties properties, DirectoryProvider<?>[] providers) provides access to sharding properties (under the suffix sharding_strategy) and provide access to all the DirectoryProviders for a given index

Method Detail

initialize

void initialize(Properties properties,
                DirectoryProvider<?>[] providers)

provides access to sharding properties (under the suffix sharding_strategy) and provide access to all the DirectoryProviders for a given index

getDirectoryProvidersForAllShards

DirectoryProvider<?>[] getDirectoryProvidersForAllShards()

Ask for all shards (eg to query or optimize)

getDirectoryProviderForAddition

DirectoryProvider<?> getDirectoryProviderForAddition(Class<?> entity,
                                                     Serializable id,
                                                     String idInString,
                                                     Document document)

return the DirectoryProvider where the given entity will be indexed

getDirectoryProvidersForDeletion

DirectoryProvider<?>[] getDirectoryProvidersForDeletion(Class<?> entity,
                                                        Serializable id,
                                                        String idInString)

return the DirectoryProvider(s) where the given entity is stored and where the deletion operation needs to be applied id and idInString can be null. If null, all the directory providers containing entity types should be returned
