Method Detail

createRdfGraph

RdfGraph createRdfGraph(java.lang.Iterable<org.openrdf.model.Statement> sts,
                        org.openrdf.model.URI graph)

Creates a RDF graph that will be passed by value.

Parameters:

graph - name (may be null)

sts - collection of the statements

Returns:

the graph

createRemoteRdfGraph

RdfGraph createRemoteRdfGraph(org.openrdf.model.URI uri)

Creates RDF graph from a remote location. If the URI could not be resolved an exception will be generated during the construction of the graph.

Parameters:

uri - to be resolved

Returns:

the constructed rdf graph

createRdfStoreConnection

RdfStoreConnection createRdfStoreConnection()

Creates a connection to local storage.

Returns:

a connection to the local store

createSPARQLEndpoint

SPARQLEndpoint createSPARQLEndpoint(org.openrdf.model.URI uri)

Creates a connection to remote SPARQL endpoint. If the URI is not resolvable or SPARQL enabled service could not be found an exception will be generated after constructing the object.

Parameters:

uri -

Returns:

sparql endpoint object

createSPARQLQuery

SPARQLQuery createSPARQLQuery(java.lang.String query)

Create a SPARQL query from a string

Parameters:

query - to be parsed

Returns:

executable query by a SPARQL endpoint

createSPARQLQuery

SPARQLQuery createSPARQLQuery(java.lang.String query,
                              org.openrdf.model.URI label)

Creates a SPARQL query from a string to be executed against a specific labeled group. The labeled group for now could not be specified as part of the syntax like the dataset in FROM/FROM NAMED clauses.

Parameters:

query - to be parsed

label - labeled group to be used (may be null)

Returns:

executable query by a SPARQL endpoint

createSPARQLQuery

SPARQLQuery createSPARQLQuery(java.lang.String query,
                              java.lang.String ns,
                              org.openrdf.model.URI label)

Creates a SPARQL query from a string to be executed against a specific labeled group. The labeled group for now could not be specified as part of the syntax like the dataset in FROM/FROM NAMED clauses.

Parameters:

query - to be parsed

ns - default namespace to be used in the expansion of the short qname in query

label - labeled group to be used (may be null)

Returns:

executable query by a SPARQL endpoint
