#define OFFLINE_CAST_CONST_METHOD

(

_Method_

)

Value:

const_cast<                               \
    std::remove_const_t<                    \
      decltype(this->_Method_)              \
    >                                       \
  >(                                        \
    static_cast<                            \
      std::add_const_t<                     \
        std::remove_reference_t<            \
          decltype(*this)                   \
        >                                   \
      >&                                    \
    >(*this)._Method_                       \
  )

To reduce unnecessary code duplication, the otherwise-identical but lengthy const and non-const methods of class can be rewritten so that only the const one has to be implemented while the other is generated by this macro. (Meyers, Effective C++) Example: original code

class Foo { Bar& GetBar(const int i); const Bar& GetBar(const int i) const; };

can be rewritten as

#include <utl/ClassHelpers.h> class Foo { Bar& GetBar(const int i) { return OFFLINE_CAST_CONST_METHOD(GetBar(i)); } const Bar& GetBar(const int i) const; };

and thus reduce the trivial boiler-plate code duplication
