SparqlRdfResultsNamespace

Namespace Uri for the RDF serialization of a SPARQL Result Set.

Methods

Load(ISparqlResultsHandler, StreamReader, IUriFactory)

Loads a SPARQL Results from RDF contained in the given Stream using a Results Handler.

Declaration
public override void Load(ISparqlResultsHandler handler, StreamReader input, IUriFactory uriFactory)
Parameters
Type Name Description
ISparqlResultsHandler handler

Results Handler to use.
StreamReader input

Stream to read from.
IUriFactory uriFactory

URI Factory to use.
Overrides
Remarks

Uses the StringParser which will use simple heuristics to 'guess' the format of the RDF unless the parser was instaniated with a specific IRdfReader to use.

Load(ISparqlResultsHandler, TextReader, IUriFactory)

Loads a SPARQL Results from RDF contained in the given Input using a Results Handler.

Declaration
public override void Load(ISparqlResultsHandler handler, TextReader input, IUriFactory uriFactory)
Parameters
Type Name Description
ISparqlResultsHandler handler

Results Handler to use.
TextReader input

Input to read from.
IUriFactory uriFactory

URI Factory to use.
Overrides
Remarks

Uses the StringParser which will use simple heuristics to 'guess' the format of the RDF unless the parser was instaniated with a specific IRdfReader to use.

Load(ISparqlResultsHandler, string, IUriFactory)

Loads a SPARQL Results from RDF contained in the given file using a Results Handler.

Declaration
public override void Load(ISparqlResultsHandler handler, string filename, IUriFactory uriFactory)
Parameters
Type Name Description
ISparqlResultsHandler handler

Results Handler to use.
string filename

File to read from.
IUriFactory uriFactory

URI Factory to use.
Overrides
Remarks

Uses the FileLoader to load the RDF from the file which will attempt to determine the format of the RDF based on the file extension unless the parser was instantiated with a specific IRdfReader to use.
