[TYPO3-dev] how to iterate over LoadedExtensionArrayElement

[Alexander Stehlik]

Hi Franz,

is there a reason why you do not use

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::isLoaded()

for that?

The code in this method is pretty simple:

$isLoaded = static::$packageManager->isPackageActive($key);
if ($exitOnError && !$isLoaded) {
	throw new \BadFunctionCallException('TYPO3 Fatal Error: Extension "' . 
$key . '" is not loaded!', 1270853910);
}
return $isLoaded;

Of course you could also directly use the isPackageActive() in the 
PackageManager.

I hope I got the point of your question right ;)

Cheers,
Alex
