Definition

template<typename BaseTraits>
class CGAL::Arr_counting_traits_2< BaseTraits >

A metadata traits-class decorator for the arrangement package.

It counts the number of invocations of traits-class functors. It is parameterized with another traits class and inherits from it. For each traits method it maintains a counter that counts the number of invocations into the method.

It models all the concepts that the original traits models.

Examples: Arrangement_on_surface_2/count_and_trace.cpp.
