DistanceMatrixApiRequest

public DistanceMatrixApiRequest(GeoApiContext context)

Method Detail

validateRequest

protected void validateRequest()

origins

public DistanceMatrixApiRequest origins(java.lang.String... origins)

One or more addresses from which to calculate distance and time. The service will geocode the strings and convert them to latitude/longitude coordinates to calculate directions.

Parameters:

origins - Strings to geocode and use as an origin point (e.g. "New York, NY")

Returns:

Returns this DistanceMatrixApiRequest for call chaining.

origins

public DistanceMatrixApiRequest origins(LatLng... points)

One or more latitude/longitude values from which to calculate distance and time.

Parameters:

points - The origin points.

Returns:

Returns this DistanceMatrixApiRequest for call chaining.

destinations

public DistanceMatrixApiRequest destinations(java.lang.String... destinations)

One or more addresses to which to calculate distance and time. The service will geocode the strings and convert them to latitude/longitude coordinates to calculate directions.

Parameters:

destinations - Strings to geocode and use as a destination point (e.g. "Jersey City, NJ")

Returns:

Returns this DistanceMatrixApiRequest for call chaining.

destinations

public DistanceMatrixApiRequest destinations(LatLng... points)

One or more latitude/longitude values to which to calculate distance and time.

Parameters:

points - The destination points.

Returns:

Returns this DistanceMatrixApiRequest for call chaining.

mode

public DistanceMatrixApiRequest mode(TravelMode mode)

Specifies the mode of transport to use when calculating directions.

Note that Distance Matrix requests only support TravelMode.DRIVING, TravelMode.WALKING and TravelMode.BICYCLING.

Parameters:

mode - One of the travel modes supported by the Distance Matrix API.

Returns:

Returns this DistanceMatrixApiRequest for call chaining.

avoid

public DistanceMatrixApiRequest avoid(DirectionsApi.RouteRestriction restriction)

Introduces restrictions to the route. Only one restriction can be specified.

Parameters:

restriction - One of DirectionsApi.RouteRestriction.TOLLS, DirectionsApi.RouteRestriction.FERRIES or DirectionsApi.RouteRestriction.HIGHWAYS.

Returns:

Returns this DistanceMatrixApiRequest for call chaining.

units

public DistanceMatrixApiRequest units(Unit unit)

Specifies the unit system to use when expressing distance as text. Distance Matrix results contain text within distance fields to indicate the distance of the calculated route.

Parameters:

unit - One of Unit.METRIC or Unit.IMPERIAL.

Returns:

Returns this DistanceMatrixApiRequest for call chaining.

Unit systems in the Distance Matrix API

departureTime

public DistanceMatrixApiRequest departureTime(java.time.Instant departureTime)

Specifies the desired time of departure.

The departure time may be specified in two cases:

• For requests where the travel mode is transit: You can optionally specify one of departure_time or arrival_time. If neither time is specified, the departure_time defaults to now. (That is, the departure time defaults to the current time.)
• For requests where the travel mode is driving: Google Maps API for Work customers can specify the departure_time to receive trip duration considering current traffic conditions. The departure_time must be set to within a few minutes of the current time.

Setting the parameter to null will remove it from the API request.

Parameters:

departureTime - The time of departure.

Returns:

Returns this DistanceMatrixApiRequest for call chaining.

trafficModel

public DistanceMatrixApiRequest trafficModel(TrafficModel trafficModel)

Specifies the assumptions to use when calculating time in traffic. This parameter may only be specified when the travel mode is driving and the request includes a departure_time.

Parameters:

trafficModel - The traffic model to use in estimating time in traffic.

Returns:

Returns this DistanceMatrixApiRequest for call chaining.

arrivalTime

public DistanceMatrixApiRequest arrivalTime(java.time.Instant arrivalTime)

Specifies the desired time of arrival for transit requests. You can specify either departure_time or arrival_time, but not both.

Parameters:

arrivalTime - The preferred arrival time.

Returns:

Returns this DistanceMatrixApiRequest for call chaining.

transitModes

public DistanceMatrixApiRequest transitModes(TransitMode... transitModes)

Specifies one or more preferred modes of transit. This parameter may only be specified for requests where the mode is transit.

Parameters:

transitModes - The preferred transit modes.

Returns:

Returns this DistanceMatrixApiRequest for call chaining.

transitRoutingPreference

public DistanceMatrixApiRequest transitRoutingPreference(TransitRoutingPreference pref)

Specifies preferences for transit requests. Using this parameter, you can bias the options returned, rather than accepting the default best route chosen by the API.

Parameters:

pref - The transit routing preference for this distance matrix.

Returns:

Returns this DistanceMatrixApiRequest for call chaining.

setCallback

public final void setCallback(PendingResult.Callback<T> callback)

Description copied from interface: PendingResult

Performs the request asynchronously, calling onResult or onFailure after the request has been completed.

Specified by:

setCallback in interface PendingResult<T>

Parameters:

callback - The callback to call on completion.

await

Description copied from interface: PendingResult

Performs the request synchronously.

Specified by:

await in interface PendingResult<T>

Returns:

The result.

ApiException - Thrown if the API Returned result is an error.

java.lang.InterruptedException - Thrown when a thread is waiting, sleeping, or otherwise occupied, and the thread is interrupted.

java.io.IOException - Thrown when an I/O exception of some sort has occurred.

awaitIgnoreError

public final T awaitIgnoreError()

Description copied from interface: PendingResult

Performs the request synchronously, ignoring exceptions while performing the request and errors returned by the server.

Specified by:
