= Старт на инстанца на линија

Инстанца на линија може да стартува само Возач.

==== Симулација на real-time сигнал од автобус
 
При старт на инстанца се испалува евент:

{{{#!div

{{{#!java

return instancaNaLinijaRepository
            .save(instanca)
            .let {
                publisher.publishEvent(StartRouteEvent(it))
                dtoMapper.toRouteInstanceResponse(it)
            }
}}}
}}}

Евентот се слуша овде:

{{{#!div
{{{#!java
@Async
    @EventListener
    fun startRouteEvent(event: StartRouteEvent) {
        println(event)
        println(event)
        val instance = event.source as InstancaNaLinija
        val line = instance.linija
        val direction = instance.pravec
        val stations = stationService.findStationsByLineIdAndDirectionId(line.id, direction.id)

        simulator.simulate(instance, stations)
    }

    @Async
    @EventListener
    fun routeInstanceOnStation(event: RouteInstanceOnStationEvent) {
        println("------------------------------------------------")
        println(event)
        val source = event.source as RouteInstanceOnStation
        routeInstanceOnStationService.create(source.instance.id, source.station.id, source.timestamp)
        // todo: publish event to the websocket so that the user gets notified
        webSocketService.sendMessage("routes", "Updated routes")
    }

    @EventListener
    fun stopRouteEvent(event: StopRouteInstanceEvent) {
        val instance = event.source as InstancaNaLinija
        routeInstanceService.stop(instance.id)
    }
}}}
}}}

Се стартува симулатор кој симулира пингови од GPS на автобус.
