Class: Service

new H.service.trafficVectorTile.Service (opt_options)

This class encapsulates the HERE Traffic Vector Tile API endpoint.

It's not allowed to call the constructor directly (an IllegalOperationError is thrown). Instead an instance of this Service can be retrieved by calling the factory method H.service.Platform#getTrafficVectorTileService on a platform instance.

Name Type Description
opt_options H.service.trafficVectorTile.Service.Options optional

Configuration options for Traffic Vector Tile service

Throws:
Example
// Assumption: the platform is instantiated
myService = platform.getTrafficVectorTileService();
