Method Details

createSinkQuads

public static SinkStreaming<org.apache.jena.sparql.core.Quad> createSinkQuads(org.apache.jena.riot.RDFFormat format,
 OutputStream out,
 org.apache.jena.shared.PrefixMapping pm,
 long prefixAnalysis,
 Supplier<org.apache.jena.query.Dataset> datasetSupp)

Create a sink that for line based format streams directly to the output stream or collects quads in memory and emits them all at once in the given format when flushing the sink.

Parameters:

r -

format -

out -

prefixAnalysisEventCount - Defer output until this number of triple/quad events have been reached and optimize prefixes for the seen data in that window. Negative values cause deferring until all events have been seen which effectively disables streaming. A value of zero immediately prints out the prefixes

dataset - The dataset implementation to use for non-streaming data. Allows for use of insert-order preserving dataset implementations.

Returns:
