Method Detail

validateRequest

protected void validateRequest()

origin

public DirectionsApiRequest origin(java.lang.String origin)

The address or textual latitude/longitude value from which you wish to calculate directions. If you pass an address as a location, the Directions service will geocode the location and convert it to a latitude/longitude coordinate to calculate directions. If you pass coordinates, ensure that no space exists between the latitude and longitude values.

Parameters:

origin - The starting location for the Directions request.

Returns:

Returns this DirectionsApiRequest for call chaining.

destination

public DirectionsApiRequest destination(java.lang.String destination)

The address or textual latitude/longitude value from which you wish to calculate directions. If you pass an address as a location, the Directions service will geocode the location and convert it to a latitude/longitude coordinate to calculate directions. If you pass coordinates, ensure that no space exists between the latitude and longitude values.

Parameters:

destination - The ending location for the Directions request.

Returns:

Returns this DirectionsApiRequest for call chaining.

origin

public DirectionsApiRequest origin(LatLng origin)

The origin, as a latitude/longitude location.

Parameters:

origin - The starting location for the Directions request.

Returns:

Returns this DirectionsApiRequest for call chaining.

destination

public DirectionsApiRequest destination(LatLng destination)

The destination, as a latitude/longitude location.

Parameters:

destination - The ending location for the Directions request.

Returns:

Returns this DirectionsApiRequest for call chaining.

mode

public DirectionsApiRequest mode(TravelMode mode)

Specifies the mode of transport to use when calculating directions. The mode defaults to driving if left unspecified. If you set the mode to TRANSIT you must also specify either a departureTime or an arrivalTime.

Parameters:

mode - The travel mode to request directions for.

Returns:

Returns this DirectionsApiRequest for call chaining.

avoid

public DirectionsApiRequest avoid(DirectionsApi.RouteRestriction... restrictions)

Indicates that the calculated route(s) should avoid the indicated features.

Parameters:

restrictions - one or more of DirectionsApi.RouteRestriction.TOLLS, DirectionsApi.RouteRestriction.HIGHWAYS, DirectionsApi.RouteRestriction.FERRIES

Returns:

Returns this DirectionsApiRequest for call chaining.

units

public DirectionsApiRequest units(Unit units)

Specifies the unit system to use when displaying results.

Parameters:

units - The preferred units for displaying distances.

Returns:

Returns this DirectionsApiRequest for call chaining.

region

public DirectionsApiRequest region(java.lang.String region)

Parameters:

Returns:

Returns this DirectionsApiRequest for call chaining.

arrivalTime

public DirectionsApiRequest arrivalTime(java.time.Instant time)

Set the arrival time for a Transit directions request.

Parameters:

time - The arrival time to calculate directions for.

Returns:

Returns this DirectionsApiRequest for call chaining.

departureTime

public DirectionsApiRequest departureTime(java.time.Instant time)

Set the departure time for a transit or driving directions request. If both departure time and traffic model are not provided, then "now" is assumed. If traffic model is supplied, then departure time must be specified.

Parameters:

time - The departure time to calculate directions for.

Returns:

Returns this DirectionsApiRequest for call chaining.

waypoints

public DirectionsApiRequest waypoints(DirectionsApiRequest.Waypoint... waypoints)

Specifies a list of waypoints. Waypoints alter a route by routing it through the specified * location(s). A waypoint is specified as either a latitude/longitude coordinate or as an address * which will be geocoded. Waypoints are only supported for driving, walking and bicycling * directions.

For more information on waypoints, see Using Waypoints in Routes.

Parameters:
