I have 2 polygons. outer and hole inside outer.

Polygon_2 outer ;

outer.push_back( Point(-1,-1) ) ;

outer.push_back( Point(0,-12) ) ;

outer.push_back( Point(1,-1) ) ;

outer.push_back( Point(12,0) ) ;

outer.push_back( Point(1,1) ) ;

outer.push_back( Point(0,12) ) ;

outer.push_back( Point(-1,1) ) ;

outer.push_back( Point(-12,0) ) ;

Polygon_2 hole ;

hole.push_back( Point(-1,0) ) ;

hole.push_back( Point(0,1 ) ) ;

hole.push_back( Point(1,0 ) ) ;

hole.push_back( Point(0,-1) ) ;

Polygon_with_holes poly( outer ) ;

poly.add_hole( hole ) ;

======

1. How I can create poly variable without initialization.

Polygon_with_holes poly;

and how add outer to poly?

is any poly.add_outer function?

2. How I can clear all point from poly. all outer and all holes?

poly.clear() or similar?
