This method clears any PolyNode children contained by PolyTree the object.

Clear does not need to be called explicitly. The Clipper.Execute method that accepts a PolyTree parameter will automatically clear the PolyTree object before propagating it with new PolyNodes. Likewise, PolyTree's destructor will also automatically clear any contained PolyNodes.

C#  » public PolyNode GetFirst();

+ + +

This method returns the first outer polygon contour if any, otherwise a null pointer.

This function is almost equivalent to calling Childs[0] except that when a PolyTree object is empty (has no children), calling Childs[0] would raise an out of range exception.
