Usage

Initialize the container (you can give the definitions into this construct) :

$container = new Container();
or
$container = new Container($definitions);

//definitions file :
return [
new \MulerTech\Container\Definition(\Psr\Http\Server\RequestHandlerInterface::class, \MulerTech\Application\RequestHandler::class),
new \MulerTech\Container\Definition(\MulerTech\Form\Validators\MaxLengthValidator::class, null, [], true)
];

Get simple class :

$container->get(Foo::class);

Add a class with its interface (you can get this class with the interface class name) :

$container->add(FooInterface::class, Foo::class);

$fooClass = $container->get(FooInterface::class);

Add a class with arguments :

$container->add(FooInterface::class, Foo::class, ['argumentName' => 'argument value']);

Set parameters and get it :

$container->setParameter('parameter', 'a value');

echo $container->getParameter('parameter'); // a value

Use parameters into class construct arguments :

$container->setParameter('parameter', 'a value');

$container->add(FooInterface::class, Foo::class, ['argumentName' => '%parameter%']);

Load yaml files parameters into container :

$container = new Container();
$loader = new Loader();
$loader
    ->setFileList(['./path_to_files/file1.yaml', './path_to_files/file2.yaml'])
    ->setLoader(YamlLoader::class)
    ->loadParameters($container);

Set parameters with env value :

#env file :
key=value

$container = new Container();
$container->setParameter('parameter', 'env(key)');
echo $container->getParameter('parameter'); // value
