## Detailed Description

The QGeoRouteRequest class represents the parameters and restrictions which define a request for routing information.

The default state of a QGeoRouteRequest instance will result in a request for basic route segment and navigation maneuvers describing the fastest route by car which covers the given waypoints.

There may be significant variation in the features supported by different providers of routing information, or even in the features supported by the same provider if different levels of authorization are used.

There are several functions in QGeoRoutingManager which can be used to check which features are supported with the current provider and authorization level.

See also QGeoRoutingManager.

### enum QGeoRouteRequest::FeatureWeight
flags QGeoRouteRequest::FeatureWeights

Defines the weight to associate with a feature during the planning of a route.

The content of the QVariantMap is somehow backend-specific, but properties that can be specified using Waypoint elements in QML can be assumed to be named and to work the same way across plugins, where supported.

See also waypointsMetadata().
