Indexed_array iterators¶
indexed_array provides random access iterators, with O(1) complexity. These iterators are
valid as long as the object exists, no operation on indexed_array does iterator
invalidation.
begin¶
These functions return an iterator to the beginning of the indexed_array. If the array is empty,
the iterator will be equal to end().
-
constexpr iterator indexed_array::begin()¶
-
constexpr const_iterator indexed_array::begin() const¶
-
constexpr const_iterator indexed_array::cbegin() const¶
end¶
These functions return an iterator which is immediately after the last element. It is undefined behaviour to try to dereference such an iterator.
-
constexpr iterator indexed_array::end()¶
-
constexpr const_iterator indexed_array::end() const¶
-
constexpr const_iterator indexed_array::cend() const¶
rbegin¶
These functions return a reverse iterator to the first element of the reversed indexed_array (which is
the last element of the array). If the array is empty, then it is equal to rend().
See https://en.cppreference.com/w/cpp/container/array/rbegin for a detailed explanation on reverse iteration.
-
constexpr reverse_iterator indexed_array::rbegin()¶
-
constexpr const_reverse_iterator indexed_array::rbegin() const¶
-
constexpr const_reverse_iterator indexed_array::crbegin() const¶
rend¶
These functions return a reverse iterator which is past the last element of the reversed indexed_array. It is undefined behaviour to try to dereference such an iterator.
-
constexpr reverse_iterator indexed_array::rend()¶
-
constexpr const_reverse_iterator indexed_array::rend() const¶
-
constexpr const_reverse_iterator indexed_array::crend() const¶
Multidimensional arrays¶
Warning
Special care should be taken when using iterators and multidimensional arrays. Iterators always iterate through the whole array, and not through the highest-rank dimension.
