Examples of RoadModel

rinde.sim.core.model.road.RoadModel
RoadModel is a model that manages a fleet of vehicles ( {@link RoadUser}s) on top of a space. The space that is used depends on the specific implementation of {@link RoadModel}. {@link RoadUser}s have a position which is represented by a {@link Point}. Generally, RoadModels are responsible for:
- adding and removing objects
- moving objects around
On top of that the RoadModel provides several functions for retrieving objects and finding the shortest path. More utilities for working with {@link RoadModel}s are defined in {@link RoadModels}. @author Rinde van Lon
