Method Detail

fetchTopic

TopicModel fetchTopic(long topicId)

fetchTopic

TopicModel fetchTopic(String key,
                      Object value)

fetchTopics

List<? extends TopicModel> fetchTopics(String key,
                                       Object value)

queryTopics

List<TopicModel> queryTopics(Object value)

queryTopics

List<? extends TopicModel> queryTopics(String key,
                                       Object value)

fetchAllTopics

Iterator<? extends TopicModel> fetchAllTopics()

storeTopic

void storeTopic(TopicModel topicModel)

Stores a rudimentary topic in the DB.

Only the topic URI and the topic type URI are stored. The topic value (simple or composite) is not stored. The "Instantiation" association is not stored.

An URI uniqueness check is performed. If the DB already contains a topic or an association with the URI passed, an exception is thrown and nothing is stored.

Parameters:

topicModel - The topic to store. Once the method returns the topic model contains: - the ID of the stored topic. - an empty URI ("") in case null was passed. - an empty simple value ("") in case null was passed.

storeTopicUri

void storeTopicUri(long topicId,
                   String uri)

storeTopicTypeUri

void storeTopicTypeUri(long topicId,
                       String topicTypeUri)

storeTopicValue

void storeTopicValue(long topicId,
                     SimpleValue value,
                     List<IndexMode> indexModes,
                     String indexKey,
                     SimpleValue indexValue)

Stores and indexes a topic value.

Parameters:

indexValue - Optional: the value to be indexed. If indexValue is not specified, value is used.
