Functions
-
template<class MAP_T, class KEY_T>
inline bool Has(const MAP_T &in_map, const KEY_T &key) Take any map type, and run find to determine if a key is present.
-
template<class MAP_T, class KEY_T>
inline void IncrementCounter(MAP_T &in_map, const KEY_T &key) Take a map where the value is an integer and a key. Increment value associated with that key if its present or if its not add it and set it to 1
-
template<typename KEY_T, typename ELEMENT_T, typename FUN_T>
bool AnyOf(const std::map<KEY_T, ELEMENT_T> &c, FUN_T fun)
-
template<typename KEY_T, typename ELEMENT_T, typename FUN_T>
bool AllOf(const std::map<KEY_T, ELEMENT_T> &c, FUN_T fun)
-
template<typename KEY_T, typename ELEMENT_T, typename FUN_T>
bool NoneOf(const std::map<KEY_T, ELEMENT_T> &c, FUN_T fun)
-
template<class MAP_T, class KEY_T>
inline auto Find(const MAP_T &in_map, const KEY_T &key, const typename MAP_T::mapped_type &dval) Take any map, run find() member function, and return the result found (or default value if no results found).
-
template<class MAP_T, class KEY_T>
inline const auto &FindRef(const MAP_T &in_map, const KEY_T &key, const typename MAP_T::mapped_type &dval) Take any map and element, run find() member function, and return a reference to the result found (or default value if no results found).
-
template<class MAP_T, class KEY_T>
inline const auto &GetConstRef(const MAP_T &in_map, const KEY_T &key) Take any map and element, run find() member function, and return a reference to the result found; trip assert if the result is not present.
-
template<typename A, typename B>
constexpr std::pair<B, A> flip_pair(const std::pair<A, B> &p) Take an std::pair<A,B> and return the flipped pair std::pair<B,A>
