Examples of ch.epfl.lbd.database.spatial.LatLngPoint

ch.epfl.lbd.database.spatial.LatLngPoint
LatLngPoint represents a geographical point express by its latitude and longitude. This object provides the methods to interact with those points as well as the methods to persist the object into the database
