Can PHPStorm recognize the returned object through a static method?

Question

PHP

I recently installed this IDE for myself, so I'm trying to figure out what it can do. It will be faster to show. There is a code:

<?php

class system {

    public function getSingleton(){
        return singleton::getInstance();
    }

}

class singleton{

    public static $instance  = null; // Инстанс объекта данного класса

    private function __construct() {}
    private function __clone() {}

    /******************************/
    /* Возвращаем инстанс объекта */
    public static function getInstance() {
        if ( is_null( self::$instance ) ) {
            self::$instance = new singleton;
        }
        return self::$instance;
    }
    /* Возвращаем инстанс объекта */
    /******************************/

    public function test() {
        echo '1';
    }
}

$system = new system();

$object = $system->getSingleton();

When I type in the $object-> line, I expect to see a singleton class methods hint, but the IDE gives me a "No suggestion" message. Is it possible to teach the IDE to recognize the returned object?

IDE version 4.0.3.

Thanks in advance for the replies.

Answer 1

the getSingleton() method needs a comment /** return singleton */

/**
 * @return singleton
 */
public function getSingleton(){

// и даже по цепочке должно работать
/**
 * @return singleton
 */
public static function getInstance() {

Answer 2

Easy way: use /** var */ as far as I understand.
Those. something like

/** @var $system singleton */

Answer 3

the getSingleton() method needs a comment /** return singleton */

/**
 * @return singleton
 */
public function getSingleton(){

// и даже по цепочке должно работать
/**
 * @return singleton
 */
public static function getInstance() {

Answer 4

Specify what type of variable your method returns, in the end, even in the factory there will be an addition, provided that each returned variable / property will have an explicitly specified type

/**
 * @var singleton
 */
public static $instance  = null; // Инстанс объекта данного класса
