27 * Method to "bootstrap" the node. This step does also apply provided
28 * command-line arguments stored in the request instance. You should now
29 * get it from calling $this->getRequestInstance().
33 function doBootstrapping ();
36 * Initializes hub-specific queues
40 function initQueues ();
43 * Outputs the console teaser. This should only be executed on startup or
44 * full restarts. This method generates some space around the teaser.
48 function outputConsoleTeaser ();
51 * Generic method to acquire a hub-id. On first run this generates a new one
52 * based on many pseudo-random data. On any later run, unless the id
53 * got not removed from database, it will be restored from the database.

60 * Activates the hub by doing some final preparation and setting
61 * $hubIsActive to true
63 * @param $requestInstance A Requestable class
64 * @param $responseInstance A Responseable class
67 function activateHub (Requestable $requestInstance, Responseable $responseInstance);
70 * Generates a session id which will be sent to the other hubs and clients
74 function bootstrapGenerateSessionId ();
77 * Initializes the listener pool (class)
81 function initializeListenerPool ();
84 * Restores a previously stored node list from database
