[![Latest Stable Version]](https://packagist.org/packages/wikimedia/scoped-callback) [![License]](https://packagist.org/packages/wikimedia/scoped-callback) ScopedCallback ============== 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](https://www.mediawiki.org/wiki/ScopedCallback). Usage ----- ```php 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 ); ``` Running tests ------------- composer install --prefer-dist composer test --- [Latest Stable Version]: https://poser.pugx.org/wikimedia/scoped-callback/v/stable.svg [License]: https://poser.pugx.org/wikimedia/scoped-callback/license.svg
