      • mapRegionChanged

        public void mapRegionChanged​(MapRegionEvent e)
        Description copied from interface: Layer
        When the associated canvas's map region is changed, this method is called to notify the layer of the change. Note that either a device window change (as a result of resizing the application window) or a data window change can cause this method to be invoked. Query the canvas' MapRegion object to get the changed values. Inside a mapRegionChanged() implementation, the layer typically needs to update its data contents accordingly.

        mapRegionChanged in interface Layer
        Overrides:
        mapRegionChanged in class NFERenderer<NFENetworkElementGeoObject>
