    Returns
    the original JSON from a flattened version
    Note
    Empty objects and arrays are flattened by flatten() to null values and can not unflattened to their original type. Apart from this example, for a JSON value j, the following is always true: j == j.flatten().unflatten().
    Complexity

    Note
    This constructor allows to pass enums directly to a constructor. As C++ has no way of specifying the type of an anonymous enum explicitly, we can only rely on the fact that such values implicitly convert to int. As int may already be the same type of number_integer_t, we may need to switch off the constructor basic_json(const number_integer_t).

    void nlohmann::basic_json::push_back (std::initializer_list< basic_json > init)
    +     		+inline
    +
    +

    This function allows to use push_back with an initializer list. In case

    +
      +
    1. the current value is an object,
      2. +
    2. the initializer list init contains only two elements, and
      3. +
    3. the first element of init is a string,
      4. +
    +

    init is converted into an object element and added using push_back(const typename object_t::value_type&). Otherwise, init is converted to a JSON value and added using push_back(basic_json&&).

    +
    Parameters
    + + +
    initan initializer list
    +
    +
    +
    Complexity
    Linear in the size of the initializer list init.
    +
    Note
    This function is required to resolve an ambiguous overload error, because pairs like {"key", "value"} can be both interpreted as object_t::value_type or std::initializer_list<basic_json>, see https://github.com/nlohmann/json/issues/235 for more information.
    +
    Example
    The example shows how initializer lists are treated as objects when possible.

    Create a null JSON value. This is the explicitly version of the null value constructor as it takes a null pointer as parameter. It allows to create null values by explicitly assigning a nullptr to a JSON value. The passed null pointer itself is not read – it is only used to choose the right constructor.

    Complexity
    Constant.
    Exception safety
    No-throw guarantee: this constructor never throws exceptions.

    43 # Container function overview
    44 
    45 The container functions known from STL have been extended to support the different value types from JSON. However, not all functions can be applied to all value types. Note that the signature of some functions differ between the types; for instance, `at` may be called with either a string to address a key in an object or with an integer to address a value in an array.
