AbstractGeometry class Routes & Navigation

Structured representation of a junction or turn geometry.

AbstractGeometry models the intersection anchor, driving side and a list of AbstractGeometryItem instances that describe how lanes, arrows and other shapes are attached to the anchor. This structure is the machine-readable source used to render a schematic of the junction or to generate the abstract geometry image via TurnDetails.getAbstractGeometryImage.

Typical fields include the anchorType (point, circle or waypoint), the driveSide (left or right), a list of items, and optional counts for intermediate turns on the left/right side.

Consumers typically use the TurnDetails.abstractGeometryImg property to obtain a ready-to-render image of the entire geometry.
