Detailed Description

template<bool IsConst, typename Type>
struct boost::geometry::add_const_if_c< IsConst, Type >

Meta-function to define a const or non const type.

If the boolean template parameter is true, the type parameter will be defined as const, otherwise it will be defined as it was. This meta-function is used to have one implementation for both const and non const references

Note

This traits class is completely independant from Boost.Geometry and might be a separate addition to Boost

Used in a.o. for_each, interior_rings, exterior_ring

Example

void foo(typename add_const_if_c<IsConst, Point>::type& point)
