# Type Jail [![Test](https://github.com/InterNations/type-jail/actions/workflows/tests.yaml/badge.svg)](https://github.com/InterNations/type-jail/actions/workflows/tests.yaml)

Enforce super type contract of an object

## Usage

```php

use InterNations\Component\TypeJail\Factory\SuperTypeFactory;

use InterNations\Component\TypeJail\Factory\JailFactory;

use InterNations\Component\TypeJail\Factory\SuperTypeJailFactory;

$file = new SplFileObject(__FILE__);

$factory = new JailFactory();

$file = $factory->createInstanceJail($file, 'SplFileInfo');

// Will return true

var_dump($file instanceof SplFileInfo);

// Will return the file path because that method is declared in SplFileInfo

$file->getFilePath();

// Will throw an exception indicating a type violation because that method

// is declared in SplFileObject

$file->flock();

$factory = new SuperTypeJailFactory();

$file = $factory->createInstanceJail($file, 'SplFileInfo');

// Will return false

var_dump($file instanceof SplFileInfo);

// Will return the file path because that method is declared in SplFileInfo

$file->getFilePath();

// Will throw an exception indicating a type violation because that method

// is declared in SplFileObject

$file->flock();

$factory = new SuperTypeFactory();

$file = $factory->createInstanceJail($file, 'SplFileInfo');

// Will return false

var_dump($file instanceof SplFileInfo);

// Will return the file path because that method is declared in SplFileInfo

$file->getFilePath();

// Fatal error: method not found

$file->flock();

```
