Class PrettyTurtleWriter

java.lang.Object
com.stardog.stark.io.turtle.TurtleWriter
com.stardog.stark.io.turtle.PrettyTurtleWriter
All Implemented Interfaces:
RDFHandler, RDFWriter
public class PrettyTurtleWriter extends TurtleWriter implements RDFWriter

An Turtle writer that abbreviates bnodes and lists. This writer requires to buffer all the triples in memory before writing so no output will be printed until end() is called. If the number of triples exceed a limit, the writer prints them as TurtleWriter, i.e. without bnode and list shortcuts.

  • Constructor Details

  • Method Details

    • start

      public void start()
      Signals that the RDF writing process is starting.
      Specified by:
      start in interface RDFHandler
      Specified by:
      start in interface RDFWriter
      Overrides:
      start in class TurtleWriter

    • handle

      public void handle(@Nonnull Statement theStmt)
      Write the given Statement
      Specified by:
      handle in interface RDFHandler
      Specified by:
      handle in interface RDFWriter
      Overrides:
      handle in class TurtleWriter
      Parameters:
      theStmt - the statement to write

    • end

      public void end()
      Signals the writing process is completed. The underlying InputStream is *not* closed, but the caller should not call additional methods on this writer as that will normally yield syntax errors in the output.
      Specified by:
      end in interface RDFHandler
      Specified by:
      end in interface RDFWriter
      Overrides:
      end in class TurtleWriter

    • comment

      public void comment(@Nonnull String theComment)
      Write a comment to the output. Writing need not be started at this point; comments can be written prior to any actual serialized RDF
      Specified by:
      comment in interface RDFWriter
      Overrides:
      comment in class TurtleWriter
      Parameters:
      theComment - the comment to write

    • namespace

      public void namespace(@Nonnull String thePrefix, @Nonnull String theIRI)
      Description copied from class: TurtleWriter
      Provide a namespace to the writer. This method can be called before writing has started, in which case, the namespace bindings are buffered and written when appropriate after writing has begun.
      Specified by:
      namespace in interface RDFHandler
      Specified by:
      namespace in interface RDFWriter
      Overrides:
      namespace in class TurtleWriter
      Parameters:
      thePrefix - the namespace prefix
      theIRI - the associated IRI

    • format

      @Nonnull public RDFFormat format()
      The format this writer will serialize output in.
      Specified by:
      format in interface RDFWriter
      Overrides:
      format in class TurtleWriter
      Returns:
      the format
