Class WKTFileReader


  • public class WKTFileReader
extends Object
    Reads a sequence of Geometrys in WKT format from a text file. The geometries in the file may be separated by any amount of whitespace and newlines.

    • Constructor Detail

      • WKTFileReader

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

      • WKTFileReader

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

      • WKTFileReader

        public WKTFileReader(Reader reader,
                     WKTReader wktReader)
        Creates a new WKTFileReader, given a Reader to read from.
        Parameters:
        reader - the reader to read from
        wktReader - the geometry reader to use

    • 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 occured reading a geometry
