Class WKBHexFileReader


  • public class WKBHexFileReader
    extends Object
    Reads a sequence of Geometrys in WKBHex format from a text file. Each WKBHex geometry must be on a single line The geometries in the file may be separated by any amount of whitespace and newlines.

    • Method Detail

      • 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
