Enumeration Type Documentation

enum VgNavigationModule::VgManeuverType

Maneuver type indications.

Enumerator
eVgManeuverTypeUnknown	Unknown maneuver type.
eVgManeuverTypeGoStraight	Go straight.
eVgManeuverTypeTurnGentleRight	Turn gentle right.
eVgManeuverTypeTurnGentleLeft	Turn gentle left.
eVgManeuverTypeTurnRight	Turn right.
eVgManeuverTypeTurnLeft	Turn left.
eVgManeuverTypeTurnSharpRight	Turn sharp right.
eVgManeuverTypeTurnSharpLeft	Turn sharp left.
eVgManeuverTypeUTurnRight	U-turn right.
eVgManeuverTypeUTurnLeft	U-turn left.
eVgManeuverTypeStart	Start of route.
eVgManeuverTypeEnd	End of route.
eVgManeuverTypeGoUp	Go up to next level. Only possible if mMergeFloorChangeInstructions is false.
eVgManeuverTypeGoDown	Go down to next level. Only possible if mMergeFloorChangeInstructions is false.
eVgManeuverTypeChangeModality	The modality has changed. Only possible if mMergeFloorChangeInstructions is false.
eVgManeuverTypeChangeLayer	The layer has changed, but it is at the same height and modality (otherwise it would be a eVgManeuverTypeGoUp or eVgManeuverTypeGoDown) usually means changing buildings. Version 2.1.2
eVgManeuverTypeWaypoint	Intermediate waypoint. Version 2.1.4
eVgManeuverTypeMax	This enum represents the maximum enum value possible (should always be last).

enum VgNavigationModule::VgModalityParameterType

An enum which contains various attributes which can be configured for a particular modality.

Version

2.0.7729

Enumerator
eStraightAngleThreshold	Threshold angle in degrees that determines how a VgIRoute will be broken into different instructions. Default value is 7.0 degrees. The larger this value is, the longer the instructions will be and the fewer instructions there will be.
eDistanceFromCouloirThreshold	The perpendicular distance threshold in meters from the active instruction, before a new instruction will be considered. Default value 2.0 meters Remarks Larger values mean longer instructions and fewer total number of instructions.
eNearPlacesThreshold	Threshold in meters to determine the places near turns for navigation instructions. default value 20.0 meters. Larger values mean more near places will be computed. Remarks Very large values can have a negative impact on the performance.
eMinimumInstructionLength	Minimum length of instructions in meters. Default value 0.0 meters. If possible, instructions with lengths smaller than this value will not be generated. Useful for avoiding small instructions at the beginning of a route.
eNumParameters	This must be kept last in the enum. Counts the values.

enum VgNavigationModule::VgNavigationRequestStatus

The status of a route request.

Enumerator
eSuccess	Request was successful.
eError	Request failure for unspecified reason.
