Deprecation: #84284 - Protected methods and properties in ContentElement/ElementInformationController¶
This file is about third party usage (consumer that call the class as well as
signals or hooks depending on it) of
A series of class properties has been set to protected. They will throw deprecation warnings if called public from outside:
All methods not used as entry points by
TYPO3\CMS\Backend\Http\RouteDispatcher will be
removed or set to protected in v10 and throw deprecation warnings if used from a third party:
Calling one of the above methods or accessing one of the above properties on an instance of
ElementInformationController will throw a deprecation warning in v9 and a PHP fatal in v10.
In general all extensions
that set properties or call methods except
mainAction() are affected.
In general, extensions should not instantiate and re-use controllers of the core. Existing usages should be rewritten to be free of calls like these.
Since some of the deprecated methods and properties have quite common names and would produce false positives, their usage is not detected by the extension scanner.
