Methods
-
dispose(
) → void -
Releases the underlying native resources. Idempotent: calling it more
than once is safe, but the object must not be used after dispose.
inherited
-
edgeDst(
int edge) → (int, Point2f) - Returns the edge destination.
-
edgeDstAsync(
int edge) → Future< (int, Point2f)> -
Available on Subdiv2D, provided by the Subdiv2DAsync extension
Returns the edge destination. -
edgeOrg(
int edge) → (int, Point2f) - Returns the edge origin.
-
edgeOrgAsync(
int edge) → Future< (int, Point2f)> -
Available on Subdiv2D, provided by the Subdiv2DAsync extension
Returns the edge origin. -
findNearest(
Point2f pt) → (int, Point2f) - Finds the subdivision vertex closest to the given point.
-
findNearestAsync(
Point2f pt) → Future< (int, Point2f)> -
Available on Subdiv2D, provided by the Subdiv2DAsync extension
Finds the subdivision vertex closest to the given point. -
freeNative(
) → void -
Frees the native resources owned by this object. Subclasses implement the
concrete free logic here; callers must use dispose instead.
