Syntax
public class TriGWriter : IStoreWriter, IHighSpeedWriter, IPrettyPrintingWriter, ICompressingWriter, IMultiThreadedWriter
Remarks

For efficiency the TriG Writer splits it's writing over several threads (currently 4), these threads share a reference to a Context object which gives Global writing context eg. the target System.IO.TextWriter being written to. Each thread generates temporary local writing contexts as it goes along, each of these is scoped to writing a specific Graph. Graphs are written to a StringWriter so the output for each Graph is built completely and then written in one go to the System.IO.TextWriter specified as the target of the writing in the global context.
