Deprecation: #68122 - Deprecate GeneralUtility::readLLfile

See Issue #68122

Description

Method GeneralUtility::realLLfile() was just a wrapper around LocalizationFactory and has been marked as deprecated.

Impact

Extensions using realLLfile() to parse localization files should switch to an instance of LocalizationFactory.

Affected Installations

Extensions using GeneralUtility::readLLfile()

Migration

A typical call now should look like:

/** @var $languageFactory \TYPO3\CMS\Core\Localization\LocalizationFactory */
$languageFactory = GeneralUtility::makeInstance(\TYPO3\CMS\Core\Localization\LocalizationFactory::class);
$languageFactory->getParsedData($fileToParse, $language, $renderCharset, $errorMode);
