+/**
+ * TApplicationComponent class
+ *
+ * TApplicationComponent is the base class for all components that are
+ * application-related, such as controls, modules, services, etc.
+ *
+ * TApplicationComponent mainly defines a few properties that are shortcuts
+ * to some commonly used methods. The {@link getApplication Application}
+ * property gives the application instance that this component belongs to;
+ * {@link getService Service} gives the current running service;
+ * {@link getRequest Request}, {@link getResponse Response} and {@link getSession Session}
+ * return the request and response modules, respectively;
+ * And {@link getUser User} gives the current user instance.
+ *
+ * Besides, TApplicationComponent defines two shortcut methods for
+ * publishing private files: {@link publishAsset} and {@link publishFilePath}.
+ *
