    • WKBHexFileReader

      public WKBHexFileReader(File file, WKBReader wkbReader)
      Creates a new WKBHexFileReader given the File to read from and a WKTReader to use to parse the geometries.
      Parameters:
      file - the File to read from
      wkbReader - the geometry reader to use

    • WKBHexFileReader

      public WKBHexFileReader(String filename, WKBReader wkbReader)
      Creates a new WKBHexFileReader, given the name of the file to read from.
      Parameters:
      filename - the name of the file to read from
      wkbReader - the geometry reader to use

    • WKBHexFileReader

      public WKBHexFileReader(Reader reader, WKBReader wkbReader)
      Creates a new WKBHexFileReader, given a Reader to read from.
      Parameters:
      reader - the reader to read from
      wkbReader - the geometry reader to use

  • Method Details

    • setLimit

      public void setLimit(int limit)
      Sets the maximum number of geometries to read.
      Parameters:
      limit - the maximum number of geometries to read

    • setOffset

      public void setOffset(int offset)
      Sets the number of geometries to skip before storing.
      Parameters:
      offset - the number of geometries to skip

    • read

      public List read() throws IOException, ParseException
      Reads a sequence of geometries. If an offset is specified, geometries read up to the offset count are skipped. If a limit is specified, no more than limit geometries are read.
      Returns:
      the list of geometries read
      Throws:
      IOException - if an I/O exception was encountered
      ParseException - if an error occurred reading a geometry
