      • WKTFileReader

        public WKTFileReader​(java.io.Reader reader,
                     WKTReader wktReader)
        Creates a new WKTFileReader, given a Reader to read from.

    • 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

      • setStrictParsing

        public void setStrictParsing​(boolean isStrict)
        Allows ignoring WKT parse errors after at least one geometry has been read, to return a partial result.
        Parameters:
        isStrict - whether to ignore parse errors

      • 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 java.util.List read()
                    throws java.io.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:
        java.io.IOException - if an I/O exception was encountered
        ParseException - if an error occurred reading a geometry
