JSON AddObjectCopyAt Example

Demonstrates the AddObjectCopyAt function.

Note: This example requires Chilkat v9.5.0.82 or above.

Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final json = CkJsonObject();
  json.load('{ "name": "John", "marbles": 100 }');

  final json2 = CkJsonObject();
  json2.load('{"street":"1200 Elm St.","city":"Springfield","zip":60606}');

  // Copy the contents of json2 to a new member object named "addr".
  // Insert it in the 2nd position.
  json.addObjectCopyAt(1, 'addr', json2);

  print(json.emit());
  // Expected output is:  {"name":"John","addr":{"street":"1200 Elm St.","city":"Springfield","zip":60606},"marbles":100}

  // Note: Modifying the contents of json does not modify the contents of json2 (because the contents of json2 were copied).
  // For example:
  json.updateString('addr.street', '1000 Oak St.');
  print(json.emit());
  // Expected output is:  {"name":"John","addr":{"street":"1000 Oak St.","city":"Springfield","zip":60606},"marbles":100}

  print(json2.emit());
  // Expected output is: {"street":"1200 Elm St.","city":"Springfield","zip":60606}
}
