| # SessionManager |
| |
| This directory contains files for managing ChromeOS user sessions. It is |
| a continuing effort to move the user session related code from UserManager |
| and UserSessionManager to this directory. |
| |
| It is put under components/ directory so that non-browser code could access |
| it. However, ash/ code should access user sessions via ash::SessionController |
| rather than this. SessionController/Client internally calls code here but |
| it provides a separation of ash and browser. It would be nice to keep it. |
| |
| The core/ directory contains the SessionManager class. It provides an interface |
| to create user sessions, add/remove observers, and check user session state. |
| User session managing methods are not ready for external code to use. They |
| are still expected to be called from the current user session starting code |
| path, i.e. UserSessionManager and ChromeSessionManager. |
| |
| SessionManager::Get() method gets the singleton like instance. The instance |
| in Chrome browser is ChromeSessionManager derived from SessionManager. This |
| is needed because SessionManager logic depends on policy code which is still |
| part of the browser. ChromeSessionManager is in browser/ and can access that. |
| The ChromeSessionManager instance is created in the PreCreateMainMessageLoop |
| stage and destroyed in the PostMainMessageLoopRun. |
