Class Method Details

.isochrone_service(version: :v1, transport: :grpc, &block) ⇒ ::Object

Create a new client object for IsochroneService.

By default, this returns an instance of Google::Maps::Isochrones::V1::IsochroneService::Client for a gRPC client for version V1 of the API. However, you can specify a different API version by passing it in the version parameter. If the IsochroneService service is supported by that API version, and the corresponding gem is available, the appropriate versioned client will be returned. You can also specify a different transport by passing :rest or :grpc in the transport parameter.

Raises an exception if the currently installed versioned client gem for the given API version does not support the given transport of the IsochroneService service. You can determine whether the method will succeed by calling isochrone_service_available?.

About IsochroneService

Service for calculating isochrones. An isochrone is an area of reachability from a given origin point within a specified travel time.

Parameters:

  • version (::String, ::Symbol) (defaults to: :v1) —

    The API version to connect to. Optional. Defaults to :v1.

  • transport (:grpc, :rest) (defaults to: :grpc) —

    The transport to use. Defaults to :grpc.

Returns:

  • (::Object) —

    A client object for the specified version.

end

.isochrone_service_available?(version: :v1, transport: :grpc) ⇒ boolean

Determines whether the IsochroneService service is supported by the current client. If true, you can retrieve a client object by calling isochrone_service. If false, that method will raise an exception. This could happen if the given API version does not exist or does not support the IsochroneService service, or if the versioned client gem needs an update to support the IsochroneService service.

Parameters:

  • version (::String, ::Symbol) (defaults to: :v1) —

    The API version to connect to. Optional. Defaults to :v1.

  • transport (:grpc, :rest) (defaults to: :grpc) —

    The transport to use. Defaults to :grpc.

Returns:

  • (boolean) —

    Whether the service is available.
