Method Detail

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<Painting,Painting,IRI>

prepareNamedSparqlSuppliers

protected RDF4JDao.NamedSparqlSupplierPreparer prepareNamedSparqlSuppliers(RDF4JDao.NamedSparqlSupplierPreparer preparer)

Specified by:

prepareNamedSparqlSuppliers in class RDF4JDao

mapSolution

protected Painting 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<Painting,Painting,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<Painting,Painting,IRI>

getInsertSparql

protected NamedSparqlSupplier getInsertSparql(Painting painting)

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<Painting,Painting,IRI>

populateBindingsForUpdate

protected void populateBindingsForUpdate(MutableBindings bindingsBuilder,
                                         Painting painting)

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<Painting,Painting,IRI>

getInputId

protected IRI getInputId(Painting painting)

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<Painting,Painting,IRI>
