Challenge 1 / 1

Suppose the following class exists:

class Bakery
{
    public function bakeBread(string $type): Bread
    {
        // ...
    }
}

How could we decorate this to do something after a bread is baked?

You can't: the class you want to decorate must implement an interface.

class DecoratedBakery extends Bakery
{
    public function bakeBread(string $type): Bread
    {
        $bread = parent::bakeBread($type);

        // some work
        return $bread;
    }
}

class DecoratedBakery
{
    public function __construct(
        private Bakery $bakery;
    ){}

    public function bakeBread(string $type): Bread
    {
        $bread = $this->bakery->bakeBread($type);

        // some work
        return $bread;
    }
}
