:mrdocs:

Change the size of this JsonArray to the specified `count`, inserting copies of the specified `json` at the end if `count > size()`. If `count < size()`, the elements in the range `[count .. size())]` are erased `json` is ignored, and this method does not throw. If `count > size()` and an exception is thrown, `*this` is unaffected. Throw `bsl::length_error` if `count > maxSize()`.
