Laravel的工厂？

Question

It appear you can write Factories in Laravel.

According to doumentation: https://laravel.com/docs/5.3/database-testing#writing-factories

It appear Factories for the model/database related.

Is it possible to write Factories for non model related?

For example of two classes:

class Car {
  public function drive() { }
} 

Class Bike {
 public function ride() { }
}

Rather than using (new Car)->drive() I would like to use Transport Factory to class the class.

Answer 1

I'd do something like this

class Transport
{
    public static function build($vehicle)
    {
        return new $vehicle;
    }
}

interface Vehicle
{
    public function drive();
}

class Car implements Vehicle
{
    public function drive()
    {
        // the way a car drives
    }
}

class Bike implements Vehicle
{
    public function drive()
    {
        // the way a bike drives
    }
}

class Something
{
    public function someFunc()
    {
        Transport::build('Car')->drive();
    }
}

Here without having separate methods like drive() and ride() for Car and Bike classes, I just added drive() method. Then Bike and Car bind to the Vehicle contract.

So then we just need to pass either a Car or a Bike to Transport::build('Car')->drive();
