Modifier and Type	Method	Description
protected IRI	convertIdToIri(ID id)	Converts the provided id to an IRI.
void	delete(ID id)	Naive implementation using RDF4JTemplate.delete(IRI).
protected void	deleteForUpdate(ID id)	When updating an entity via RDF4JCRUDDao.save(Object), its triples are removed first using this method.
protected ID	generateNewId(ID providedId)	Generates a new id for an entity.
final ENTITY	getById(ID id)	Obtains the entity with the specified id, throwing an exception if none is found.
final Optional<ENTITY>	getByIdOptional(ID id)	Obtains an optional entity with the specified id.
protected ID	getInputId(ENTITY input)	Obtains the id of the input instance or null if it is new (or a partially populated composite key).
protected NamedSparqlSupplier	getInsertSparql(ENTITY input)	Returns the SPARQL string used to write an instance of T to the database.
protected String	getReadQuery()	Returns the SPARQL string used to read an instance of T from the database.
protected NamedSparqlSupplier	getUpdateSparql(ENTITY input)	Returns the SPARQL string used to update an instance of T in the database.
final List<ENTITY>	list()
protected ENTITY	mapSolution(BindingSet querySolution)	Map one solution of the readQuery to the type of this DAO.
protected static BindingsBuilder	newBindingsBuilder()	Returns a new BindingsBuilder for your convenience.
protected void	populateBindingsForUpdate(MutableBindings bindingsBuilder, ENTITY input)	Sets the non-id bindings on for the write query such that the instance of type I is written to the database.
protected abstract void	populateIdBindings(MutableBindings bindingsBuilder, ID id)	Binds the instance id to query variable(s).
protected ENTITY	postProcessMappedSolution(ENTITY entity)	Callback invoked after mapping a solution to an entity, allowing subclasses to modify the entity before returning it to the client.
protected void	postProcessUpdate(ENTITY input, Map<String,Value> bindings)	Callback invoked after a successful insert/update.
final ENTITY	save(ENTITY input)	Saves the entity, loads it again and returns it.
ID	saveAndReturnId(ENTITY input)
ID	saveAndReturnId(ENTITY input, ID id)	Saves the entity and returns its (possibly newly generated) ID.

protected String	getNamedSparqlString(String key)
protected NamedSparqlSupplier	getNamedSparqlSupplier(String key)	Obtains the NamedSparqlSupplier with the specified key for use in, e.g., RDF4JTemplate.tupleQuery(Class, NamedSparqlSupplier).
protected TupleQueryEvaluationBuilder	getNamedTupleQuery(String key)
protected UpdateExecutionBuilder	getNamedUpdate(String key)
