LatLonRect (NetCDF-Java CDM API v5.3.3)

java.lang.Object
- ucar.unidata.geoloc.LatLonRect

```
public class LatLonRect
extends Object
```
Bounding box for latitude/longitude points. This is a rectangle in lat/lon coordinates. This class handles the longitude wrapping problem. The Rectangle always starts from lowerLeft, goes east width degrees until upperRight For latitude, lower < upper. Since the longitude must be in the range +/-180., right may be less or greater than left.

public LatLonRect(LatLonPoint p1,
                  double deltaLat,
                  double deltaLon)
```
    Construct a lat/lon bounding box from a point, and a delta lat, lon. This disambiguates which way the box wraps around the globe.
    
    Parameters:
    
    p1 - one corner of the box
    
    deltaLat - delta lat from p1. (may be positive or negetive)
    
    deltaLon - delta lon from p1. (may be positive or negetive)
  - LatLonRect
```
public LatLonRect(LatLonPoint left,
                  LatLonPoint right)
```
    Construct a lat/lon bounding box from two points. The order of longitude coord of the two points matters: pt1.lon is always the "left" point, then points contained within the box increase (unless crossing the Dateline, in which case they jump to -180, but then start increasing again) until pt2.lon The order of lat doesnt matter: smaller will go to "lower" point (further south)
    
    Parameters:
    
    left - left corner
    
    right - right corner
  - LatLonRect
```
public LatLonRect(String spec)
```
    Construct a lat/lon bounding box from a string.
    
    Parameters:
    
    spec - "lat, lon, deltaLat, deltaLon"
