Operations

As in the Kernel concept, for each of the function objects above, there must exist a member function that requires no arguments and returns an instance of that function object.

The name of the member function is the uncapitalized name of the type returned with the suffix _object appended. For example, for the function object CircularKernel::Construct_circular_arc_2 the following member function must exist:

Construct_circular_arc_2 construct_circular_arc_2_object () const
