Deprecation: #68074 - Deprecate getPageRenderer() methods 

See forge#68074

Description 

The following public functions have been marked as deprecated as the instance they return is a singleton:

  • TYPO3\CMS\Backend\Controller\BackendController::getPageRenderer()
  • TYPO3\CMS\Backend\Template\DocumentTemplate::getPageRenderer()
  • TYPO3\CMS\Backend\Template\FrontendDocumentTemplate::getPageRenderer()
  • TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController::getPageRenderer()

Impact 

Using one of these functions will throw a deprecation message.

Migration 

As the PageRenderer implements a SingletonInterface you can get your own (shared) instance with \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\TYPO3\CMS\Core\Page\PageRenderer::class) and work with that one.
