How is the dot operator _location.InRangeOf being used here for the tower's location?

I understand that the invader's location is being called with invader.Location. What is tripping me up is that we're using _location.InRangeOf when InRangeOf is not even a method in the same class.

This is the more complete context.

namespace TreehouseDefense
{
   class Tower
   {
       private readonly MapLocation _location;

       public Tower(MapLocation location)
       {
         _location = location;
       }

       public void FireOnInvaders(Invader[] invaders)
       {
         foreach(Invader invader in invaders)
         {
            if(_location.InRangeOf(invader.Location, 1))
            {
                invader.DecreaseHealth(1);
            }
         }
       }
   }

And the InRangeOf method is written in a different file:

        public bool InRangeOf(MApLocation location, int range)
        {
            return DistanceTo(location) <+ range;
        }

Thank you!
