Struct Documentation¶

struct cursor¶

the cursor type

Public Functions

cursor() = default¶: constructs an uninitialized cursor

inline cursor(RangeNest *range)¶: constructs a cursor pointing to the begin, if range is not empty

Note

has O(1) complexity

inline cursor(RangeNest *range, ranges::default_sentinel_t)¶: constructs a cursor pointing to the end

Note

has O(1) complexity

inline cursor(RangeNest *range, typename RangeNest::iterator range_iter, typename Range::iterator elem_iter)¶: constructs a cursor pointing to particular range_iter and elem_iter

Note

has O(N) complexity due to the need to compute the ordinal

inline const auto &read() const¶

inline bool equal(const cursor &that) const¶

inline void next()¶

inline const auto range_iter() const¶

Returns:: the iterator pointing to the range in which this is located

inline const auto range_ordinal() const¶

Returns:: ordinal index of the range in which this is located

inline const auto elem_iter() const¶

Returns:: the iterator pointing to the element at which this is located

inline const auto ordinal() const¶

Returns:: ordinal index of the element at which this is located (i.e. distance to the first element of the first range)

inline void erase()¶: calls erase on the current iterator

template<typename T> inline void insert(T &&elem)¶: calls insert on the current iterator
