Class: MultiRoute

alk.source.MultiRoute

An instance of this class provides a source that may lookup routes between two or more stops.

new alk.source.MultiRoute(opt_options)

This constructor creates a Source object that accesses the ALK Routing engine and the capability to handle multiple routes.

If the 'hubRouting' option is 'true', then the first stop is considered the 'hub' and the last stop is represented as a numbered circle in the ordered chain of stops.

A Stop is represented as a generic ol.Feature with a ol.geom.Point geometry. The route between Stops is represented by a @{link ol.Feature} with a ol.geom.LineString or ol.geom.MultiLineString geometry. All features that belong to a particular route get tagged with the 'routeId' attribute. All stops are tagged with the 'stop' attribute, which contains the original coordinates given to the alk.source.MultiRoute#addRoute function. All stops are also tagged with a "stopIndex" attribute indicating the ordinal index in the given stop list, i.e. start stop is '0'. Stops are also tagged with a 'stopType' attribute, designating alk.val.StopType.Origin for the first (start) stop, alk.val.StopType.Destination for the last stop, and //TODO: what are the other stops designated as? If the 'hubRouting' option is true, all features, including lines are tagged with the 'hubRouting' attribute, and the last stop does not carry the 'Destination' type.

The option contains the Dataset parameter for the Service. This option specifies an area dataset that may be pertinent to the request.
hostURL string

This option contains the the host and port URL for the particular service. This option is not set by the user, but is automatically generated from the particular service being used.

This option is the path part of the URL for the particular service. This option is not set by the user, but is automatically generated from the particular service being used.
region alk.val.Region | number | string

This option tells the service in which region the retrieved data is to pertain. Some ALK Services switch underlying services due to this option. For instance, traffic data for North America and Europe may come from different underlying services.
