java.util.stream.Stream<? extends org.apache.commons.rdf.api.Triple>	read(java.io.InputStream input, java.lang.String context, org.apache.commons.rdf.api.RDFSyntax syntax)	Read an input stream into a stream of triples
void	update(org.apache.commons.rdf.api.Graph graph, java.lang.String update, java.lang.String context)	Apply a Sparql-Update operation over a Graph
void	write(java.util.stream.Stream<? extends 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<? extends 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<? extends org.apache.commons.rdf.api.Triple> read(java.io.InputStream input,
                                                                          java.lang.String context,
                                                                          org.apache.commons.rdf.api.RDFSyntax syntax)

Read an input stream into a stream of triples

Parameters:

input - the input stream

context - the RDF context

syntax - the RDF syntax

Returns:

a stream of triples

update

void update(org.apache.commons.rdf.api.Graph graph,
            java.lang.String update,
            java.lang.String context)

Apply a Sparql-Update operation over a Graph

Parameters:

graph - the input graph

update - the sparql-update request

context - the context to resolve relative IRIs
