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

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

Create a `JsonObject` having the same value as the specified `original`. Use the specified `basicAllocator` to supply memory. If `basicAllocator == original.allocator()` the value of `original` will be moved (in constant time) to the newly‐created `JsonObject`, and `original` will be left in a valid but unspecified state. Otherwise, `original` is copied, and `basicAllocator` used to supply memory.

Create a `JsonObject` having members created (in order) from the specified `memberInitializers`. Member initializers having key values that were previously inserted into the new object are ignored. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is not specified, the currently installed default allocator is used. The behavior is undefined unless the key of each member initializer in `memberInitializers` is valid UTF‐8 (see `bdlde::Utf8Util::isValid`).

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`).
