Macro Definition Documentation

CODI_DECLARE_DEFAULT

#define CODI_DECLARE_DEFAULT	(		Type,
			Default )   Type

CODI_IDE can be defined to use the default declaration of type names. This enables auto completion in the IDEs.

Every using declaration in all CoDiPack classes should declare its variables as: using TYPE = CODI_DECLARE_DEFAULT(T_TYPE, Default);

CODI_ENABLE_CHECK

#define CODI_ENABLE_CHECK	(		option,
			condition )   (!(option) || (condition))

Check the condition only if the option is true, otherwise the result is always true. Used like if(CODI_ENABLE_CHECK(option, condition)) {...}, option == false means that the if body is always executed.

CODI_WRAP_FUNCTION

#define CODI_WRAP_FUNCTION	(		NAME,
			FUNC )

Value:

  struct NAME {                               \
    public:                                   \
                            \
      template<typename... Args>              \
      void operator()(Args&&... args) const { \
        FUNC(std::forward<Args>(args)...);    \
      }                                       \
  }

Wrap a function in a function object. Used for performance optimizations.

CODI_WRAP_FUNCTION_TEMPLATE

#define CODI_WRAP_FUNCTION_TEMPLATE	(		NAME,
			FUNC )

Value:

  template<typename... TT>                        \
  struct NAME {                                   \
    public:                                       \
                                \
      template<typename... Args>                  \
      void operator()(Args&&... args) const {     \
        FUNC<TT...>(std::forward<Args>(args)...); \
      }                                           \
  }

Wrap a function in a function object. Used for performance optimizations.
