How to let PhpStorm to know more about my static methods?

AbstractObject.php

<?php


abstract class AbstractObject
{
    // we use static var to enforce setting up entry point
    // in child classes
    public static $entryPoint = null;

    public static function getEntryPoint()
    {
        // late static binding let us to get entry point value
        // in concrete child class
        if (is_null(static::$entryPoint)) {
            $className = static::class;
            throw new \UnexpectedValueException("You must setup entry point for $className type objects ");
        }

        return static::$entryPoint;
    }
}

Address.php

<?php


class Address extends AbstractClass
{
    // we setup entry point
    // which will be used in Service
    public static $entryPoint = 'address';
}

client.php

<?php

$service = new Service();
// user sends just 1) query string and 2) type/class of objects he want to get response for
$object = $service->getObject('Tour de Eiffel', Address::class);
// next time a user probably would like to get a company data
$google = $service->getObject("Google", Company::class);

Service.php

<?php


class Service
{

    // now I would like a user/client to pass 1) query string and 2) class of objects
    // in form Address::class
    public function getObject(string $query, string $fqcn)
    {
        // PhpStorm can find (as it should!) getEntryPoint() method in $template class
        // what should i do?
        
        // Looks like adding annotation below solves the problem
        /** @var AbstractObject $fqcn */
        $response = $this->getResponse($query, $fqcn::getEntryPoint());

        // some logic applied here to return to a user needed result;
        return $object;
    }

    private function getResponse($query, $entryPoint)
    {
        // build full url for API entry point and
        // actually asks API
        return new stdClass();
    }
}
