Description

JsonObjectConst::size() returns the number of key-value pairs in the object pointed by the JsonObjectConst.

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

If you want to loop over each key-value pair in the object, use iterators.

Signature

size_t size() const;

Return value

JsonObjectConst::size() return an unsigned integer that contains the number of key-value pairs in the object.
