Interface IOService

All Known Implementing Classes:

JenaIOService

public interface IOService

The IOService defines methods for reading, writing and updating RDF streams to/from a concrete RDF 1.1 syntax.

Method Summary

Modifier and Type	Method and Description
Stream<Triple>	read(InputStream input, RDFSyntax syntax, String context) Read an input stream into a stream of triples.
List<RDFSyntax>	supportedReadSyntaxes() Retrieve the set of valid syntaxes for read operations.
List<RDFSyntax>	supportedUpdateSyntaxes() Retrieve the set of valid syntaxes for update operations.
List<RDFSyntax>	supportedWriteSyntaxes() Retrieve the set of valid syntaxes for write operations.
void	update(Graph graph, String update, RDFSyntax syntax, String context) Apply a Sparql-Update operation over a Graph.
void	write(Stream<Triple> triples, OutputStream output, RDFSyntax syntax, IRI... profiles) Serialize the triple stream in a concrete RDF syntax.

Method Detail

write

void write(Stream<Triple> triples,
           OutputStream output,
           RDFSyntax syntax,
           IRI... profiles)

Serialize the triple stream in a concrete RDF syntax.

Parameters:

triples - the stream of triples

output - the output stream

syntax - the output format

profiles - additional profile information used for output

read

Stream<Triple> read(InputStream input,
                    RDFSyntax syntax,
                    String context)

Read an input stream into a stream of triples.

Parameters:

input - the input stream

syntax - the RDF syntax

context - the RDF context

Returns:

a stream of triples

update

void update(Graph graph,
            String update,
            RDFSyntax syntax,
            String context)

Apply a Sparql-Update operation over a Graph.

Parameters:

graph - the input graph

update - the sparql-update request

syntax - the RDF syntax

context - the context to resolve relative IRIs

supportedReadSyntaxes

List<RDFSyntax> supportedReadSyntaxes()

Retrieve the set of valid syntaxes for read operations.

Returns:

the syntaxes for reading resources.

supportedWriteSyntaxes

List<RDFSyntax> supportedWriteSyntaxes()

Retrieve the set of valid syntaxes for write operations.

Returns:

the syntaxes for writing resources.

supportedUpdateSyntaxes

List<RDFSyntax> supportedUpdateSyntaxes()

Retrieve the set of valid syntaxes for update operations.

Returns:

the syntaxes for updating resources.
