  * Application is the base class for all application classes.
  *
- * An application serves as the global context that the user request
- * is being processed. It manages a set of application components that
- * provide specific functionalities to the whole application.
- *
- * The core application components provided by Application are the following:
- * <ul>
- * <li>{@link getErrorHandler errorHandler}: handles PHP errors and
- *   uncaught exceptions. This application component is dynamically loaded when needed.</li>
- * <li>{@link getSecurityManager securityManager}: provides security-related
- *   services, such as hashing, encryption. This application component is dynamically
- *   loaded when needed.</li>
- * <li>{@link getStatePersister statePersister}: provides global state
- *   persistence method. This application component is dynamically loaded when needed.</li>
- * <li>{@link getCache cache}: provides caching feature. This application component is
- *   disabled by default.</li>
- * </ul>
- *
- * Application will undergo the following life cycles when processing a user request:
- * <ol>
- * <li>load application configuration;</li>
- * <li>set up class autoloader and error handling;</li>
- * <li>load static application components;</li>
- * <li>{@link beforeRequest}: preprocess the user request; `beforeRequest` event raised.</li>
- * <li>{@link processRequest}: process the user request;</li>
- * <li>{@link afterRequest}: postprocess the user request; `afterRequest` event raised.</li>
- * </ol>
- *
- * Starting from lifecycle 3, if a PHP error or an uncaught exception occurs,
- * the application will switch to its error handling logic and jump to step 6 afterwards.
