JSON AppendArrayCopy Example

Demonstrates the AppendArrayCopy 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 jarr = CkJsonArray();
  jarr.load('[ 1, 2, 3, "apple", "orange", [ 10, 20, 30 ], { "name": "Alfred"} ]');

  // Copy the contents of jar to a new array member named "stuff".
  json.appendArrayCopy('stuff', jarr);

  print(json.emit());
  // Expected output is:  {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}

  // Note: The contents of the array were copied.
  // If we modify the contents of jarr, it does not modify the array contained within "json" because it is a separate copy.
  // For example:
  jarr.addIntAt(-1, 2020);
  print(jarr.emit());
  // Expected output: [1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"},2020]

  print(json.emit());
  // Remains unchanged: {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}
}
