It delegates the analysis of those components to [`ClassChecker](https://github.com/vimeo/psalm/blob/master/src/Psalm/Checker/ClassChecker.php), [`InterfaceChecker`](https://github.com/vimeo/psalm/blob/master/src/Psalm/Checker/InterfaceChecker.php) and [`FunctionChecker`](https://github.com/vimeo/psalm/blob/master/src/Psalm/Checker/FunctionChecker.php).
