JSON AppendObjectCopy Example

Demonstrates the AppendObjectCopy function.

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

Delphi ActiveX

uses
    Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
    Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Chilkat_TLB;

...

procedure TForm1.Button1Click(Sender: TObject);
var
json: TChilkatJsonObject;
json2: TChilkatJsonObject;

begin
json := TChilkatJsonObject.Create(Self);
json.Load('{ "name": "John", "marbles": 100 }');

json2 := TChilkatJsonObject.Create(Self);
json2.Load('{"street":"1200 Elm St.","city":"Springfield","zip":60606}');

// Copy the contents of json2 to a new member object named "addr".
json.AppendObjectCopy('addr',json2.ControlInterface);

Memo1.Lines.Add(json.Emit());
// Expected output is:  {"name":"John","marbles":100,"addr":{"street":"1200 Elm St.","city":"Springfield","zip":60606}}

// 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.');
Memo1.Lines.Add(json.Emit());
// Expected output is:  {"name":"John","marbles":100,"addr":{"street":"1000 Oak St.","city":"Springfield","zip":60606}}

Memo1.Lines.Add(json2.Emit());
// Expected output is: {"street":"1200 Elm St.","city":"Springfield","zip":60606}
