-/**
- * TApplication class.
- *
- * TApplication coordinates modules and services, and serves as a configuration
- * context for all Prado components.
- *
- * TApplication uses a configuration file to specify the settings of
- * the application, the modules, the services, the parameters, and so on.
- *
- * TApplication adopts a modular structure. A TApplication instance is a composition
- * of multiple modules. A module is an instance of class implementing
- * {@link IModule} interface. Each module accomplishes certain functionalities
- * that are shared by all Prado components in an application.
- * There are default modules and user-defined modules. The latter offers extreme
- * flexibility of extending TApplication in a plug-and-play fashion.
- * Modules cooperate with each other to serve a user request by following
- * a sequence of lifecycles predefined in TApplication.
- *
- * TApplication has four modes that can be changed by setting {@link setMode Mode}
- * property (in the application configuration file).
- * - Off mode will prevent the application from serving user requests.
- * - Debug mode is mainly used during application development. It ensures
- * the cache is always up-to-date if caching is enabled. It also allows
- * exceptions are displayed with rich context information if they occur.
- * - Normal mode is mainly used during production stage. Exception information
- * will only be recorded in system error logs. The cache is ensured to be
- * up-to-date if it is enabled.
- * - Performance mode is similar to Normal mode except that it
- * does not ensure the cache is up-to-date.
- *
- * TApplication dispatches each user request to a particular service which
- * finishes the actual work for the request with the aid from the application
- * modules.
- *
- * TApplication maintains a lifecycle with the following stages:
- * - [construct] : construction of the application instance
- * - [initApplication] : load application configuration and instantiate modules and the requested service
- * - BeginRequest : this event happens right after application initialization
- * - Authentication : this event happens when authentication is needed for the current request
- * - PostAuthentication : this event happens right after the authentication is done for the current request
- * - Authorization : this event happens when authorization is needed for the current request
- * - PostAuthorization : this event happens right after the authorization is done for the current request
- * - LoadState : this event happens when application state needs to be loaded
- * - PostLoadState : this event happens right after the application state is loaded
- * - PreRunService : this event happens right before the requested service is to run
- * - RunService : this event happens when the requested service runs
- * - PostRunService : this event happens right after the requested service finishes running
- * - SaveState : this event happens when application needs to save its state
- * - PostSaveState : this event happens right after the application saves its state
- * - EndRequest : this is the last stage an application runs
- * - [destruct] : destruction of the application instance
- * Modules and services can attach their methods to one or several of the above
- * events and do appropriate processing when the events are raised. By this way,
- * the application is able to coordinate the activities of modules and services
- * in the above order. To terminate an application before the whole lifecycle
- * completes, call {@link completeRequest}.
- *
- * Examples:
- * - Create and run a Prado application:
- *
- * $application=new TApplication($configFile);
- * $application->run();
- *
- * - The parsed application configuration file is cached.
- *
- * $application=new TApplication($configFile,$cacheFile);
- * $application->run();

+/**
+ * TApplication class.
+ *
+ * TApplication coordinates modules and services, and serves as a configuration
+ * context for all Prado components.
+ *
+ * TApplication uses a configuration file to specify the settings of
+ * the application, the modules, the services, the parameters, and so on.
+ *
+ * TApplication adopts a modular structure. A TApplication instance is a composition
+ * of multiple modules. A module is an instance of class implementing
+ * {@link IModule} interface. Each module accomplishes certain functionalities
+ * that are shared by all Prado components in an application.
+ * There are default modules and user-defined modules. The latter offers extreme
+ * flexibility of extending TApplication in a plug-and-play fashion.
+ * Modules cooperate with each other to serve a user request by following
+ * a sequence of lifecycles predefined in TApplication.
+ *
+ * TApplication has four modes that can be changed by setting {@link setMode Mode}
+ * property (in the application configuration file).
+ * - Off mode will prevent the application from serving user requests.
+ * - Debug mode is mainly used during application development. It ensures
+ * the cache is always up-to-date if caching is enabled. It also allows
+ * exceptions are displayed with rich context information if they occur.
+ * - Normal mode is mainly used during production stage. Exception information
+ * will only be recorded in system error logs. The cache is ensured to be
+ * up-to-date if it is enabled.
+ * - Performance mode is similar to Normal mode except that it
+ * does not ensure the cache is up-to-date.
+ *
+ * TApplication dispatches each user request to a particular service which
+ * finishes the actual work for the request with the aid from the application
+ * modules.
+ *
+ * TApplication maintains a lifecycle with the following stages:
+ * - [construct] : construction of the application instance
+ * - [initApplication] : load application configuration and instantiate modules and the requested service
+ * - BeginRequest : this event happens right after application initialization
+ * - Authentication : this event happens when authentication is needed for the current request
+ * - PostAuthentication : this event happens right after the authentication is done for the current request
+ * - Authorization : this event happens when authorization is needed for the current request
+ * - PostAuthorization : this event happens right after the authorization is done for the current request
+ * - LoadState : this event happens when application state needs to be loaded
+ * - PostLoadState : this event happens right after the application state is loaded
+ * - PreRunService : this event happens right before the requested service is to run
+ * - RunService : this event happens when the requested service runs
+ * - PostRunService : this event happens right after the requested service finishes running
+ * - SaveState : this event happens when application needs to save its state
+ * - PostSaveState : this event happens right after the application saves its state
+ * - EndRequest : this is the last stage an application runs
+ * - [destruct] : destruction of the application instance
+ * Modules and services can attach their methods to one or several of the above
+ * events and do appropriate processing when the events are raised. By this way,
+ * the application is able to coordinate the activities of modules and services
+ * in the above order. To terminate an application before the whole lifecycle
+ * completes, call {@link completeRequest}.
+ *
+ * Examples:
+ * - Create and run a Prado application:
+ *
+ * $application=new TApplication($configFile);
+ * $application->run();
+ *
+ * - The parsed application configuration file is cached.
+ *
+ * $application=new TApplication($configFile,$cacheFile);
+ * $application->run();
