Hi Dmitry,
thanks for responding so briefly

the one question i still have, how to initiate the factory in magento to access via the object. i still struggle between how to use factorys and interfaces. i heared it is bad practice to use the objectManager. so i do not really know ho to inject or initialize the factory

many thanks for any advice

cheers Ludwig

I use just \Magento\Framework\App\ObjectManager::getInstance()

github.com

mage2pro/core/blob/1.8.8/Core/lib/objects.php#L106-L112


/**
* 2015-08-13
* @used-by df_o()
* @used-by df_ic()
* @return \Magento\Framework\ObjectManagerInterface|\Magento\Framework\App\ObjectManager
*/
function df_om() {return \Magento\Framework\App\ObjectManager::getInstance();}

github.com

mage2pro/core/blob/1.8.8/Core/lib/objects.php?ts=4#L27-L35


/**
* 2016-01-06
* @param string $resultClass
* @param array(string => mixed) $params [optional]
* @return \Magento\Framework\DataObject|object
*/
function df_create($resultClass, array $params = []) {
	return df_om()->create($resultClass, ['data' => $params]);
}

E.g:

github.com

mage2pro/core/blob/1.8.8/Directory/lib/currency.php?ts=4#L56-L79


/**
* 2016-07-04
* «How to load a currency by its ISO code?» https://mage2.pro/t/1840
* @param Currency|string|null $currency [optional]
* @return Currency
*/
function df_currency($currency = null) {
	/** @var Currency $result */
	if (!$currency) {
		$result = df_currency_base();
	}
	else if ($currency instanceof Currency) {
		$result = $currency;
	}
	else {
		/** @var array(string => Currency) $cache */
		static $cache;
		if (!isset($cache[$currency])) {
			$cache[$currency] = df_create(Currency::class)->load($currency);
		}
		$result = $cache[$currency];
	}
	return $result;
}
