DtTerrainGridLineDrawer& DtTerrainGridLineDrawer::operator=

(

const DtTerrainGridLineDrawer &

)

Note that both the copy constructor and = operator simply copy the pointer to the coordiate system.

If the object that is passed in has allocated the coordiate system, be aware that if that object deletes it's coordinate system, this will cause the application to exhibit unstable behavior
