ym.modules.provider.LatLng

Overview

Represents a geographical point with a specific latitude and longitude.

var latlng = ym.latLng(50.5, 30.5);

All leaflet methods that accept LatLng objects also accept them in simple array and object form (unless otherwise specified). These lines are equivalent:

map.panTo([50, 30]);
map.panTo({lon: 30, lat: 50});
map.panTo({lat: 50, lng: 30});
map.panTo(ym.latLng(50, 30));

otherLatlng   LatLng  

Return

bool

toString() ab v3

Returns a string representation of the dot (for debugging purposes)

Return
