Constructor Summary

GeoRSSData(String filename, DirectPosition2D latLon)
Creates a GeoRSSData object that stores the name of the file that the entry's information is written to and the geo location of the entry.

Method Summary

String	getFileName() Returns the name of the file where the entry's info is saved.
DirectPosition2D	getLatLon()
double	getX() Returns the Java 2D x-coordinate for the longitude.
double	getY() Returns the Java 2D y-coordinate for the latitude.
static HashMap<String,String>	loadFromFile(String fullFileName) Reads the file that contains the GeoRSS entry's information and returns a HashMap of key, value pairs where the key is the name of the element e.g.
