      • collisionFreeOrdered

        public static java.util.List<org.mapsforge.core.mapelements.MapElementContainer> collisionFreeOrdered​(java.util.List<org.mapsforge.core.mapelements.MapElementContainer> input)
        Transforms a list of MapElements, orders it and removes those elements that overlap. This operation is useful for an early elimination of elements in a list that will never be drawn because they overlap.
        Parameters:
        input - list of MapElements
        Returns:
        collision-free, ordered list, a subset of the input.
