nlohmann::basic_json::basic_json | ( | const basic_json & | other | ) |

inline

Creates a copy of a given JSON value.

Parameters

  [in] | other | the JSON value to copy

Complexity
  Linear in the size of other.

Requirements
  This function satisfies the Container requirements:
  - The complexity is linear.
  - As postcondition, it holds: `other == basic_json(other)`.

Exceptions

  std::bad_alloc | if allocation for object, array, or string fails.

Example
  The following code shows an example for the copy constructor.
  #include <json.hpp>
  using namespace nlohmann;
  int main()
  {
  // create a JSON array
  json j1 = {"one", "two", 3, 4.5, false};
  // create a copy
  json j2(j1);
  // serialize the JSON array
  std::cout << j1 << " = " << j2 << '\n';
  std::cout << std::boolalpha << (j1 == j2) << '\n';
  }

  Output (play with this example online):

      ["one","two",3,4.5,false] = ["one","two",3,4.5,false]
      true

  The example code above can be translated with

      g++ -std=c++11 -Isrc doc/examples/basic_json__basic_json.cpp -o basic_json__basic_json
