Interface IOService

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
java.util.stream.Stream<org.apache.commons.rdf.api.Triple>	read(java.io.InputStream input, org.apache.commons.rdf.api.RDFSyntax syntax, java.lang.String context) Read an input stream into a stream of triples.
java.util.List<org.apache.commons.rdf.api.RDFSyntax>	supportedReadSyntaxes() Retrieve the set of valid syntaxes for read operations.
java.util.List<org.apache.commons.rdf.api.RDFSyntax>	supportedUpdateSyntaxes() Retrieve the set of valid syntaxes for update operations.
java.util.List<org.apache.commons.rdf.api.RDFSyntax>	supportedWriteSyntaxes() Retrieve the set of valid syntaxes for write operations.
void	update(org.apache.commons.rdf.api.Graph graph, java.lang.String update, org.apache.commons.rdf.api.RDFSyntax syntax, java.lang.String context) Apply a Sparql-Update operation over a Graph.
void	write(java.util.stream.Stream<org.apache.commons.rdf.api.Triple> triples, java.io.OutputStream output, org.apache.commons.rdf.api.RDFSyntax syntax, org.apache.commons.rdf.api.IRI... profiles) Serialize the triple stream in a concrete RDF syntax.

Method Detail

write

void write(java.util.stream.Stream<org.apache.commons.rdf.api.Triple> triples,
           java.io.OutputStream output,
           org.apache.commons.rdf.api.RDFSyntax syntax,
           org.apache.commons.rdf.api.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

java.util.stream.Stream<org.apache.commons.rdf.api.Triple> read(java.io.InputStream input,
                                                                org.apache.commons.rdf.api.RDFSyntax syntax,
                                                                java.lang.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(org.apache.commons.rdf.api.Graph graph,
            java.lang.String update,
            org.apache.commons.rdf.api.RDFSyntax syntax,
            java.lang.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

java.util.List<org.apache.commons.rdf.api.RDFSyntax> supportedReadSyntaxes()

Retrieve the set of valid syntaxes for read operations.

Returns:

the syntaxes for reading resources.

supportedWriteSyntaxes

java.util.List<org.apache.commons.rdf.api.RDFSyntax> supportedWriteSyntaxes()

Retrieve the set of valid syntaxes for write operations.

Returns:

the syntaxes for writing resources.

supportedUpdateSyntaxes

java.util.List<org.apache.commons.rdf.api.RDFSyntax> supportedUpdateSyntaxes()

Retrieve the set of valid syntaxes for update operations.

Returns:

the syntaxes for updating resources.
