Package ucar.nc2.ft2.simpgeometry

Class SimpleGeometryReader

  • public class SimpleGeometryReader
extends Object
    A class which given a dataset, will read from the dataset one of the simple geometry types. Those being polygon, line, or point.

    • Constructor Detail

      • SimpleGeometryReader

        public SimpleGeometryReader​(NetcdfDataset ds)
        Constructs a new Simple Geometry Reader over the specified dataset.
        Parameters:
        ds - - the specified dataset

    • Method Detail

      • readPolygon

        public Polygon readPolygon​(String name,
                           int index)
        Returns a Polygon given a variable name and the geometric index. If the Polygon is not found it will return null. If the Polygon is a part of the Multi-Polygon, it will return the head (the first Polygon in the series which constitutes the Multi-Polygon).
        Parameters:
        name - of the variable which holds the Polygon
        index - of the Polygon within the variable
        Returns:
        a new polygon with all associated information

      • readLine

        public Line readLine​(String name,
                     int index)
        Returns a Line given a variable name and the geometric index. If the Line is not found it will return null. If the Line is a part of the Multi-Line, it will return the head (the first Line in the series which constitutes the Multi-Line).
        Parameters:
        name - of the variable which holds the Line
        index - of the Line within the variable
        Returns:
        a new line with all associated information

      • readPoint

        public Point readPoint​(String name,
                       int index)
        Returns a Point given a variable name and the geometric index. If the Point is not found it will return null. If the Point is a part of the Multi-Point, it will return the head (the first Point in the series which constitutes the Multi-Point).
        Parameters:
        name - of the variable which holds the Point
        index - of the Point within the variable
        Returns:
        a new Point with all associated information

      • getGeometryType

        public GeometryType getGeometryType​(String name)
        Given a variable name, returns the geometry type which that variable is associated with. If the variable has no simple geometry information, null will be returned.
        Parameters:
        name - variable name which will have geometry type be checked
        Returns:
        Geometry Type if holds geometry information, null if not
