## [DirectionsRendererOptions](https://developers.google.com/maps/documentation/javascript/reference/3.63/directions.md.txt#DirectionsRendererOptions)
interface


`google.maps.DirectionsRendererOptions`

This property will be ignored if `suppressInfoWindows` is set to `true`. |
| `map optional` | **Type:** `Map optional` Map on which to display the directions. |
| `markerOptions optional` | **Type:** `MarkerOptions optional` Options for the markers. All markers rendered by the `DirectionsRenderer` will use these options. |

| `stopover optional` | **Type:** `boolean optional` **Default:** `true` If `true`, indicates that this waypoint is a stop between the origin and destination. This has the effect of splitting the route into two legs. If `false`, indicates that the route should be biased to go through this waypoint, but not split into two legs. This is useful if you want to create a route in response to the user dragging waypoints on a map. |

## [DirectionsGeocodedWaypoint](https://developers.google.com/maps/documentation/javascript/reference/3.63/directions.md.txt#DirectionsGeocodedWaypoint)
interface


`google.maps.DirectionsGeocodedWaypoint`

| `place_id optional` | **Type:** `string optional` The place ID associated with the waypoint. Place IDs uniquely identify a place in the Google Places database and on Google Maps. Learn more about [Place IDs](https://developers.google.com/maps/documentation/places/web-service/place-id.md.txt) in the Places API developer guide. |
| `types optional` | **Type:** `Array<string> optional` An array of strings denoting the type of the returned geocoded element. For a list of possible strings, refer to the [Address Component Types](https://developers.google.com/maps/documentation/javascript/geocoding.md.txt#GeocodingAddressTypes) section of the Developer's Guide. |

## [DirectionsRoute](https://developers.google.com/maps/documentation/javascript/reference/3.63/directions.md.txt#DirectionsRoute)
interface


`google.maps.DirectionsRoute`
interface

| ### Properties ||
|---|---|
| `bounds` | **Type:** `LatLngBounds` The bounds for this route. |
| `copyrights` | **Type:** `string` Copyrights text to be displayed for this route. |
| `legs` | **Type:** `Array<DirectionsLeg>` An array of `DirectionsLeg`s, each of which contains information about the steps of which it is composed. There will be one leg for each stopover waypoint or destination specified. So a route with no stopover waypoints will contain one `DirectionsLeg` and a route with one stopover waypoint will contain two. |
| `overview_path` | **Type:** `Array<LatLng>` An array of `LatLng`s representing the entire course of this route. The path is simplified in order to make it suitable in contexts where a small number of vertices is required (such as Static Maps API URLs). |
| `overview_polyline` | **Type:** `string` An [encoded polyline representation](https://developers.google.com/maps/documentation/utilities/polylinealgorithm.md.txt) of the route in overview_path. This polyline is an approximate (smoothed) path of the resulting directions. |
| `summary` | **Type:** `string` Contains a short textual description for the route, suitable for naming and disambiguating the route from alternatives. |
| `warnings` | **Type:** `Array<string>` Warnings to be displayed when showing these directions. |
| `waypoint_order` | **Type:** `Array<number>` If `optimizeWaypoints` was set to `true`, this field will contain the re-ordered permutation of the input waypoints. For example, if the input was: Origin: Los Angeles Waypoints: Dallas, Bangor, Phoenix Destination: New York and the optimized output was ordered as follows: Origin: Los Angeles Waypoints: Phoenix, Dallas, Bangor Destination: New York then this field will be an `Array` containing the values \[2, 0, 1\]. Note that the numbering of waypoints is zero-based. If any of the input waypoints has `stopover` set to `false`, this field will be empty, since route optimization is not available for such queries. |
| `fare optional` | **Type:** `TransitFare optional` The total fare for the whole transit trip. Only applicable to transit requests. |

## [DirectionsLeg](https://developers.google.com/maps/documentation/javascript/reference/3.63/directions.md.txt#DirectionsLeg)

|---|---|
| `end_address` | **Type:** `string` The address of the destination of this leg. This content is meant to be read as-is. Do not programmatically parse the formatted address. |
| `end_location` | **Type:** `LatLng` The `DirectionsService` calculates directions between locations by using the nearest transportation option (usually a road) at the start and end locations. `end_location` indicates the actual geocoded destination, which may be different than the `end_location` of the last step if, for example, the road is not near the destination of this leg. |
| `start_address` | **Type:** `string` The address of the origin of this leg. This content is meant to be read as-is. Do not programmatically parse the formatted address. |
| `start_location` | **Type:** `LatLng` The `DirectionsService` calculates directions between locations by using the nearest transportation option (usually a road) at the start and end locations. `start_location` indicates the actual geocoded origin, which may be different than the `start_location` of the first step if, for example, the road is not near the origin of this leg. |
| `steps` | **Type:** `Array<DirectionsStep>` An array of `DirectionsStep`s, each of which contains information about the individual steps in this leg. |

| `via_waypoints` | **Type:** `Array<LatLng>` An array of non-stopover waypoints along this leg, which were specified in the original request. **Deprecated in alternative routes** . Version 3.27 will be the last version of the API that adds extra `via_waypoints` in alternative routes. When using the Directions Service to implement draggable directions, it is recommended to disable dragging of alternative routes. Only the main route should be draggable. Users can drag the main route until it matches an alternative route. |
| `arrival_time optional` | **Type:** `Time optional` An estimated arrival time for this leg. Only applicable for TRANSIT requests. |
| `departure_time optional` | **Type:** `Time optional` An estimated departure time for this leg. Only applicable for TRANSIT requests. |

interface


`google.maps.DirectionsStep`
interface

| `travel_mode` | **Type:** `TravelMode` The mode of travel used in this step. |
| `distance optional` | **Type:** `Distance optional` The distance covered by this step. This property may be `undefined` as the distance may be unknown. |

interface


`google.maps.Place`

| `location optional` | **Type:** `LatLng|LatLngLiteral optional` The `LatLng` of the entity described by this place. |
| `placeId optional` | **Type:** `string optional` The place ID of the place (such as a business or point of interest). The place ID is a unique identifier of a place in the Google Maps database. Note that the `placeId` is the most accurate way of identifying a place. If possible, you should specify the `placeId` rather than a `query`. A place ID can be retrieved from any request to the Places API, such as a [TextSearch](https://developers.google.com/maps/documentation/places/web-service/search). Place IDs can also be retrieved from requests to the Geocoding API.

| `query optional` | **Type:** `string optional` A search query describing the place (such as a business or point of interest). An example query is "Quay, Upper Level, Overseas Passenger Terminal 5 Hickson Road, The Rocks NSW". If possible, you should specify the `placeId` rather than a `query`. The API does not guarantee the accuracy of resolving the query string to a place. If both the `placeId` and `query` are provided, an error occurs. |
