mapping

问题 I have a "linestring" (with init and end points) and a single "point" (two coordinates). And I have implemented the following ActionSctipt code to use "haversine formula" to calculate the distance between two points (each point has x & y coordinates); this function can return the "distance" in "kms", "meters", "feets" or "miles": private function distanceBetweenCoordinates(lat1:Number, lon1:Number, lat2:Number, lon2:Number, units:String = "miles"):Number { var R:int = RADIUS_OF_EARTH_IN_MILES

问题 I've been trying to use AutoMapper to save some time going from my DTOs to my domain objects, but I'm having trouble configuring the map so that it works, and I'm beginning to wonder if AutoMapper might be the wrong tool for the job.
