Create an empty `JsonObject`, and then create a `Json` object for each iterator in the range starting at the specified `first` iterator and ending immediately before the specified `last` iterator, by converting from the object referred to by each iterator. Insert into this `JsonObject` each such object, ignoring those having a key that appears earlier in the sequence. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is not supplied, the currently installed default allocator is used to supply memory. The (template parameter) type `t_INPUT_ITERATOR` shall meet the requirements of an input iterator defined in the C++11 standard [24.2.3]providing access to values of a type convertible to `Member`. The behavior is undefined unless `first` and `last` refer to a sequence of valid values where `first` is at a position at or before `last`, and all keys of all `Member` objects inserted are valid UTF‐8 (see `bdlde::Utf8Util::isValid`).
