Method Details

consumeConnection

public void consumeConnection(Consumer<RepositoryConnection> fun)

applyToConnection

public <T> T applyToConnection(Function<RepositoryConnection,T> fun)

update

public UpdateExecutionBuilder update(String updateString)

Bypassing any caches, generates a new Update from the specified SPARQL string and returns a Builder for its execution. Should be avoided in favor of one of the methods that apply caching unless the update is not reusable.

update

public UpdateExecutionBuilder update(Class<?> owner,
 String operationName,
 Supplier<String> updateStringSupplier)

Uses a cached Update if one is available under the specified operationName for the RepositoryConnection that is used, otherwise the query string is obtained from the specified supplier, a new Update is instantiated and cached for future calls to this method.

Note: this call is equivalent to update(String) if operation caching is disabled.

Parameters:

owner - the class of the client requesting the update, used to generate a cache key in combination with the operation name

operationName - name of the operation that, within the scope of the client, identifies the update

updateStringSupplier - supplies the sparql of the update if needed

updateFromResource

public UpdateExecutionBuilder updateFromResource(Class<?> owner,
 String resourceName)

Reads the update from the specified resource and provides it through a in update(Class, String, Supplier), using the resourceName as the operationName.

update

public UpdateExecutionBuilder update(Class<?> owner,
 NamedSparqlSupplier namedSparqlSupplier)

Uses the provided NamedSparqlSupplier for calling update(Class, String, Supplier).

updateWithoutCachingStatement

public UpdateExecutionBuilder updateWithoutCachingStatement(String updateString)

updateWithBuilder

public UpdateWithModelBuilder updateWithBuilder()

tupleQuery

public TupleQueryEvaluationBuilder tupleQuery(String queryString)

Bypassing any caches, generates a new TupleQuery from the specified SPARQL string and returns a Builder for its evaluation. Should be avoided in favor of one of the methods that apply caching unless the query is not reusable.

tupleQuery

public TupleQueryEvaluationBuilder tupleQuery(Class<?> owner,
 String operationName,
 Supplier<String> queryStringSupplier)

Uses a cached TupleQuery if one is available under the specified operationName for the RepositoryConnection that is used, otherwise the query string is obtained from the specified supplier, a new TupleQuery is instantiated and cached for future calls to this method.

tupleQueryFromResource

public TupleQueryEvaluationBuilder tupleQueryFromResource(Class<?> owner,
 String resourceName)

Reads the query from the specified resource and provides it through a in tupleQuery(Class, String, Supplier), using the resourceName as the operationName.

tupleQuery

public TupleQueryEvaluationBuilder tupleQuery(Class<?> owner,
 NamedSparqlSupplier namedSparqlSupplier)

Uses the provided NamedSparqlSupplier for calling tupleQuery(Class, String, Supplier).

graphQuery

public GraphQueryEvaluationBuilder graphQuery(String graphQueryString)

Bypassing any caches, generates a new GraphQuery from the specified SPARQL string and returns a Builder for its evaluation. Should be avoided in favor of one of the methods that apply caching unless the query is not reusable.

graphQuery

public GraphQueryEvaluationBuilder graphQuery(Class<?> owner,
 String operationName,
 Supplier<String> queryStringSupplier)

Uses a cached GraphQuery if one is available under the specified operationName for the RepositoryConnection that is used, otherwise the query string is obtained from the specified supplier, a new GraphQuery is instantiated and cached for future calls to this method.

graphQueryFromResource

public GraphQueryEvaluationBuilder graphQueryFromResource(Class<?> owner,
 String resourceName)

Reads the query from the specified resource and provides it through a in graphQuery(Class, String, Supplier), using the resourceName as the operationName.

graphQuery

public GraphQueryEvaluationBuilder graphQuery(Class<?> owner,
 NamedSparqlSupplier namedSparqlSupplier)

Uses the provided NamedSparqlSupplier for calling graphQuery(Class, String, Supplier).

deleteTriplesWithSubject

public void deleteTriplesWithSubject(IRI id)

delete

public void delete(IRI id)

Deletes the specified resource: all triples are deleted in which id is the subject or the object.

Parameters:

id -

delete

public void delete(IRI start,
 List<PropertyPath> propertyPaths)

Deletes the specified resource and all resources R reached via any of the specified property paths.

Deletion means that all triples are removed in which start or any resource in R are the subject or the object.

Parameters:

start - the initial resource to be deleted

propertyPaths - paths by which to reach more resources to be deleted.

associate

public void associate(IRI fromResource,
 IRI property,
 Collection<IRI> toResources,
 boolean deleteOtherOutgoing,
 boolean deleteOtherIcoming)

getStringSupplierFromResourceContent

public Supplier<String> getStringSupplierFromResourceContent(String resourceName)

Returns a that returns the String content of the specified resource (as obtained by a ResourceLoader). The resource's content is read once when this method is called (revealing any problem reading the resource early on.

getNewUUID

public IRI getNewUUID()

Returns a UUID IRI (schema: 'urn:uuid'). Actual implementation depends on the uuidSource that has been configured. See UUIDSource and org.eclipse.rdf4j.spring.uuidsource for details.
