JsonArrayConst::size() gets the number of elements in the array pointed by the JsonArrayConst.

If the JsonArrayConst is null, this function returns 0.

Internally, this function walks a linked-list to count the elements, so its time complexity is O(n).

Don’t use this function to create a for loop; instead, use iterators.


size_t size() const;

Return value

JsonArrayConst::size() returns an unsigned integer containing the number of elements in the array.
