Modifier and Type	Method	Description
protected IRI	convertIdToIri(IRI id)	Converts the provided id to an IRI.
void	delete(IRI id)	Naive implementation using RDF4JTemplate.delete(IRI).
protected void	deleteForUpdate(IRI id)	When updating an entity via RDF4JCRUDDao.save(Object), its triples are removed first using this method.
protected IRI	generateNewId(IRI providedId)	Generates a new id for an entity.
final Artist	getById(IRI id)	Obtains the entity with the specified id, throwing an exception if none is found.
final Optional<Artist>	getByIdOptional(IRI id)	Obtains an optional entity with the specified id.
protected NamedSparqlSupplier	getUpdateSparql(Artist input)	Returns the SPARQL string used to update an instance of T in the database.
final List<Artist>	list()
protected static BindingsBuilder	newBindingsBuilder()	Returns a new BindingsBuilder for your convenience.
protected Artist	postProcessMappedSolution(Artist 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(Artist input, Map<String,Value> bindings)	Callback invoked after a successful insert/update.
final Artist	save(Artist input)	Saves the entity, loads it again and returns it.
IRI	saveAndReturnId(Artist input)
IRI	saveAndReturnId(Artist input, IRI id)	Saves the entity and returns its (possibly newly generated) ID.

public ArtistDao(RDF4JTemplate rdf4JTemplate)

Method Details

populateIdBindings

protected void populateIdBindings(MutableBindings bindingsBuilder,
 IRI iri)

Description copied from class: RDF4JCRUDDao

Binds the instance id to query variable(s).

Specified by:

populateIdBindings in class RDF4JCRUDDao<Artist,Artist,IRI>

populateBindingsForUpdate

protected void populateBindingsForUpdate(MutableBindings bindingsBuilder,
 Artist artist)

Description copied from class: RDF4JCRUDDao

Sets the non-id bindings on for the write query such that the instance of type I is written to the database. ID bindings are set through populateIdBindings()

Overrides:

populateBindingsForUpdate in class RDF4JCRUDDao<Artist,Artist,IRI>

mapSolution

protected Artist mapSolution(BindingSet querySolution)

Description copied from class: RDF4JCRUDDao

Map one solution of the readQuery to the type of this DAO.

Overrides:

mapSolution in class RDF4JCRUDDao<Artist,Artist,IRI>

getReadQuery

protected String getReadQuery()

Description copied from class: RDF4JCRUDDao

Returns the SPARQL string used to read an instance of T from the database. The base implementation will cache the query string, so implementations should not try to cache the query.

Overrides:

getReadQuery in class RDF4JCRUDDao<Artist,Artist,IRI>

getInsertSparql

protected NamedSparqlSupplier getInsertSparql(Artist artist)

Description copied from class: RDF4JCRUDDao

Returns the SPARQL string used to write an instance of T to the database. The instance to be inserted is passed to the function so implementations can decide which query to use based on the instance.

Overrides:

getInsertSparql in class RDF4JCRUDDao<Artist,Artist,IRI>

getInputId

protected IRI getInputId(Artist artist)

Description copied from class: RDF4JCRUDDao

Obtains the id of the input instance or null if it is new (or a partially populated composite key).

Overrides:

getInputId in class RDF4JCRUDDao<Artist,Artist,IRI>

prepareNamedSparqlSuppliers

protected RDF4JDao.NamedSparqlSupplierPreparer prepareNamedSparqlSuppliers(RDF4JDao.NamedSparqlSupplierPreparer preparer)

Specified by:

prepareNamedSparqlSuppliers in class RDF4JDao

getArtistsWithoutPaintings

public Set<Artist> getArtistsWithoutPaintings()
