Make a callback run when a dummy object leaves the scope.
The ScopedCallback class allows for running a function after the instance goes out of scope. It can be useful for making sure teardown or cleanup functions run even if exceptions are thrown. It also makes for a cleaner API for developers, by not requiring the callback to be called manually each time.
Additional documentation about the library can be found on MediaWiki.org.
use Wikimedia\ScopedCallback; $sc = new ScopedCallback( [ $this, 'teardown' ] ); // Even if this throws an exception, the callback will run // or it'll run at the end of the function $this->fooBar(); // If you want to manually call the callback ScopedCallback::consume( $sc ); // or unset( $sc ); // If you want to prevent it from being called ScopedCallback::cancel( $sc );
