This property can be used to define if loop links are allowed in datasets. A loop link is one, where the first and last vertex is the same.


If AllowLoops is false (default), loop links will be reported during the import process.


If AllowLoops is true, the existence of any loop links will prevent the use of TRoute, TRouteCalc and TDrivingDirections.


We recommend that loop links are split into 2 links in advance.


Databases without loop links: TomTom, Navteq, OSM, ITN and Meridian 2.

Databases with loop links: NVDB and DAV.


Type: Boolean
