sinkNull

public static StreamRDF sinkNull()

Send everything to nowhere ... efficiently

writer

public static StreamRDF writer(OutputStream out)

writer

public static StreamRDF writer(AWriter out)

writer

public static StreamRDF writer(Writer out)

writer

public static StreamRDF writer(OutputStream out,
                               CharSpace charSpace)

public static StreamRDF writer(AWriter out,
                               CharSpace charSpace)

public static StreamRDF writer(Writer out,
                               CharSpace charSpace)

graph

public static StreamRDF graph(Graph graph)

dataset

public static StreamRDF dataset(DatasetGraph dataset)

triplesToStream

public static void triplesToStream(StreamRDF dest,
                                   Iterator<Triple> iter)

Set triples to a StreamRDF - does not call .start/.finish

quadsToStream

public static void quadsToStream(StreamRDF dest,
                                 Iterator<Quad> iter)

Set quads to a StreamRDF - does not call .start/.finish

sinkTriples

public static StreamRDF sinkTriples(Sink<Triple> sink)

Output to a sink; prefix and base handled only within the parser. Unfortunately, Java needs different names for the triples and quads versions because of type erasure.

sinkQuads

public static StreamRDF sinkQuads(Sink<Quad> sink)

Output to a sink; prefix and base handled only within the parser. Unfortunately, Java needs different names for the triples and quads versions because of type erasure.

extendTriplesToQuads

public static StreamRDF extendTriplesToQuads(StreamRDF base)

Convert any triples seen to a quads, adding a graph node of Quad.tripleInQuad

extendTriplesToQuads

public static StreamRDF extendTriplesToQuads(Node graphNode,
                                             StreamRDF base)

Convert any triples seen to a quads, adding the specified graph node

count

public static StreamRDFCounting count()

count

public static StreamRDFCounting count(StreamRDF other)
