Cannot build a class called statically in PHP

Question

I have this structure:

class MyCollection extends BaseCollection
{

    public function getEntityCLass() : string
    {
        return Item::class;
    }

}

The base collection looks like this:

abstract class BaseCollection {
   public function __construct(array $elements = array())
    {
        foreach ($elements as $entity) {
            $this->add($entity);
        }
    }
}

This makes no sense to me ; getEntityClass should return a string but returns Item::class.

Sending an array to the class works but I honestly don't know why. Anyone care to explain?

Item::class is a short way of giving a string for the full class, it isn't a method or an object.

For instance.

Instead of Big\Massive\Long\Namespaced\ClassOfSomeSort, so long as you have imported that class with a use statement you can say ClassOfSomeSort::class which will give you the long string.
