Examples of rinde.sim.core.model.road.GraphRoadModel

rinde.sim.core.model.road.GraphRoadModel
A {@link RoadModel} that uses a {@link Graph} as road structure.{@link RoadUser}s can only be added on nodes on the graph. This model assumes that the {@link Graph} does not change. Modifying the graph afterpassing it to the model may break this model. The graph can define {@link Connection} specific speed limits using {@link MultiAttributeData}. @author Rinde van Lon @author Bartosz Michalik changes wrt.models infrastructure
