Models

Models extend Backbone.Model if no other information is given

Stops

  • Extends: Collection
  • Just a collection of stops

Line

  • Arguments: line id, colours (foreground, background)
  • Contains a collection of stops
  • Fetches stops from the server using paths like /lines/:line_id/stops

Vehicle

  • Arguments: journey id, vehicle type
  • Takes trip information in the following format: {destX: 123, destY: 123, time: 123}
  • Trips have a custom setter-method which sets the this.time and this.destination attributes, otherwise it wouldn't be possible to have separate change events for time and destination
  • Receives updates from the websocket server and triggers events for the view.

Views

Line

  • Contains a canvas for Raphael and info like end stations and line name
  • Iterates through the Line collection to find typical travel times and calculates relative pixel distances
  • NEEDS:
    • In the line model:
      • id, name, totalTime, stops
    • In the stop model:
      • time
  • Currently renders it self when, and only when, the stops collection in the line model fires the reset event.

Stop

  • Draws itself as a dot and a text.
  • Params: needs a shape and a reference to its paper/canvas

Vehicle

  • Reacts to events in the Vehicle model:
    • change:time: if vehicle is moving, change animation to reflect new time. Otherwise, do nothing?
    • trainLeftStation: starts the vehicle moving towards the current destination.
