Deprecation: #83475 - Aggregate validator information in class schema

Description

The method \TYPO3\CMS\Extbase\Mvc\Controller\ActionController::getActionMethodParameters has been marked as deprecated and will be removed in TYPO3 v10.0

Impact

The method was not considered public API and it is unlikely that the methods is used in the wild. If you rely on that method, please migrate your code base.

Affected Installations

All installations that use that method.

Migration

Use the ClassSchema class and get all necessary information from it. Example:

$reflectionService = $objectManager->get(\TYPO3\CMS\Extbase\Reflection\ReflectionService::class);
$methods = $reflectionService->getClassSchema($className)->getMethods();
$actions = array_filter($methods, function($method){
    return $method['isAction'];
});
