###Basic
```json
{
"name": "Onur YILDIZ",
"vip": true,
"telephones": ["000000000", "111111111111"],
"age": 24,
"size": 1.72,
"adresses": [
{
"adress": "blabla",
"city": "Antalya",
"pc": 7160
},
{
"adress": "blabla",
"city": "Adana",
"pc": 1170
}
]
}
```

###Delphi Side

```pascal
// foo
var
X: ISuperObject;
begin
X := SO;
X.S['name'] := 'Onur YILDIZ';
X.B['vip'] := true;
with X.A['telephones'] do
begin
Add('000000000');
Add('111111111111');
end;
X.I['age'] := 24;
X.F['size'] := 1.72;
with X.A['adresses'].O[0] {Auto Create} do
begin
S['adress'] := 'blabla';
S['city'] := 'Antalya';
I['pc'] := 7160;
end;
// or
X.A['adresses'].O[1].S['adress'] := 'blabla';

Collection (Limited)
```pascal

----------
###Marshalling **Attributes**
```pascal
TTest = class
public

Typ: String;
[ALIAS('Unit')]
Unt: Integer;
[REVAL('', '*')]
Filter: String;
[DISABLE]
BlaBlaBla: String;

Arr: TArray<String>;
end;

var X: Test;

X := TTest.Create;
X.Typ := 'XType';
X.Unt := 2;
X.Filter := '';

```
***Output***
```json

"Unit": 2,
"Filter": "*",
"Arr": null
