Operations

Additionally, for each of the predicate and construction functor types listed above, there is a member function that requires no arguments and returns an instance of that functor type.

The name of the member function is the uncapitalized name of the type returned with the suffix _object appended. For example, for the functor type Construct_vector_2 the following member function exists:

template<class OutputIterator >
OutputIterator copy_rectangle_vertices_2 (const Rectangle_2 &r, OutputIterator o) const
 copies the four vertices of r in counterclockwise order to o.
 
template<class OutputIterator >
OutputIterator copy_parallelogram_vertices_2 (const Parallelogram_2 &p, OutputIterator o) const
 copies the four vertices of p in counterclockwise order to o.
 
template<class OutputIterator >
OutputIterator copy_strip_lines_2 (const Strip_2 &s, OutputIterator o) const
 copies the two lines bounding s to o.
 
Construct_vector_2 construct_vector_2_object () const
