Declared in `<bdljsn_json.h>`

Create an empty `JsonArray`. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is not specified, the currently installed default allocator is used.

Create a `JsonArray` having the same value as the specified `original` object by moving (in constant time) the contents of `original` to the new `JsonArray` object. The allocator associated with `original` is propagated for use in the newly‐created `JsonArray` object. `original` is left in a valid but unspecified state.

Create a `JsonArray` having the same value as the specified `original` object that uses the specified `basicAllocator` to supply memory. The contents of `original` are moved (in constant time) to the new `JsonArray` object if `basicAllocator == original.allocator()`, and are move‐inserted (in linear time) using `basicAllocator` otherwise. `original` is left in a valid but unspecified state.

Create a `JsonArray` having a `Json` object for each element (in order) of the specified `elements`. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is not specified, the currently installed default allocator is used.

Create a `JsonArray` and insert (in order) each `Json` object in the range starting at the specified `first` element, and ending immediately before the specified `last` element. Optionally specify `basicAllocator` used to supply memory. If `basicAllocator` is not specified, the currently installed default allocator is used. Throw `bsl::length_error` if the number of elements in `[first .. last)]` exceeds the value returned by the method `maxSize`. 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 `Json`, and `Json` must be `emplace‐constructible` form `*i`, where `i` is a dereferenceable iterator in the range `[first .. last)]`. The behavior is undefined unless `first` and `last` refer to a range of valid values where `first` is at a position at or before `last`.
