StreamRDFLib

public StreamRDFLib()

Method Detail

sinkNull

public static StreamRDF sinkNull()

Send everything to nowhere ... efficiently

print

public static StreamRDF print(java.io.OutputStream out)

Create a StreamRDF that prints to an OutputStream. This is debug output.

writer

public static StreamRDF writer(java.io.OutputStream out)

Create a StreamRDF that outputs to an OutputStream. It is important to call StreamRDF.start() and StreamRDF.finish() because the output is buffered.

writer

public static StreamRDF writer(org.apache.jena.atlas.io.AWriter out)

Create a StreamRDF that outputs to an AWriter.

writer

public static StreamRDF writer(java.io.Writer out)

Create a StreamRDF that outputs to an Writer. It is important to call StreamRDF.start() and StreamRDF.finish() because the output is buffered.

writer

public static StreamRDF writer(java.io.OutputStream out,
                               org.apache.jena.atlas.lib.CharSpace charSpace)

Create a StreamRDF that outputs to an OutputStream with a specific CharSpace (ASCII or UTF-8).

It is important to call StreamRDF.start() and StreamRDF.finish() because the output is buffered.

writer

public static StreamRDF writer(org.apache.jena.atlas.io.AWriter out,
                               org.apache.jena.atlas.lib.CharSpace charSpace)

Create a StreamRDF that outputs to an OutputStream with a specific CharSpace (ASCII or UTF-8).

It is important to call StreamRDF.start() and StreamRDF.finish() because the output is buffered.

writer

public static StreamRDF writer(java.io.Writer out,
                               org.apache.jena.atlas.lib.CharSpace charSpace)

Create a StreamRDF that outputs to an Writer with a specific CharSpace (ASCII or UTF-8) writing out-of-range codepoints (if ASCII) as "\ uXXXX".

It is important to call StreamRDF.start() and StreamRDF.finish() because the output is buffered.

graph

public static StreamRDF graph(Graph graph)

dataset

public static StreamRDF dataset(DatasetGraph dataset)

sinkTriples

public static StreamRDF sinkTriples(org.apache.jena.atlas.lib.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(org.apache.jena.atlas.lib.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)
