  • Method Details

    • parse

      public void parse(RDFHandler theHandler) throws IOException, InvalidRDF, RDFHandlerException
      Description copied from interface: RDFStream
      Parses the stream and passes the statements to the given handler.
      Specified by:
      parse in interface RDFStream
      Throws:
      IOException
      InvalidRDF
      RDFHandlerException

    • getContext

      public Resource getContext()
      Description copied from interface: RDFStream
      Returns the default context associated with this stream or null if there is no default context. Note that, the statements that will be sent to the handler may not be using this context and the user of this stream should make sure the context information is used correctly.
      Specified by:
      getContext in interface RDFStream

    • hasContext

      public boolean hasContext()
      Description copied from interface: RDFStream
      Returns true either if this stream has a non-null context or the statements generated by this stream has contexts.
      Specified by:
      hasContext in interface RDFStream

    • getName

      public String getName()
      Description copied from interface: RDFStream
      Returns the name of this stream. If the stream is backed by a file this will return the file's name. Otherwise it might be an auto-generated name or some other (not necessarily unique) name.
      Specified by:
      getName in interface RDFStream

    • bytesRead

      public long bytesRead()
      Description copied from interface: RDFStream
      Supposed to return the number currently parsed. Can be used for progress reporting from RDFHandler
      Specified by:
      bytesRead in interface RDFStream
      Returns:
      Number of bytes parsed

    • length

      public long length()
      Specified by:
      length in interface RDFStream
      Returns:
      Length in bytes of underlying data

    • estimatedCount

      public long estimatedCount()
      Description copied from interface: RDFStream
      Estimated size of statements. Might be accurate or calculate only from the data size. Given N bytes in an RDFStream, the estimated number of statements depends on the RDF format. RDF stream may or may not be compressed, which also impacts the bytes-to-statements ratio.
      Specified by:
      estimatedCount in interface RDFStream
      Returns:
      estimated size of statements.
