void Hyperspace::Master::handle_sleep ( )

Handle sleep event (e.g.

laptop close). This method works in conjunction with handle_wakeup() to allow Hyperspace to continue working after the machine on which it is running has been suspended and resumed, for example when the laptop is closed and then reopened. It records the current time in m_sleep_time, which is then used by handle_wakeup() to extend session leases.

Definition at line 1829 of file Master.cc.

void Hyperspace::Master::handle_wakeup ( )

Handle wakeup event (e.g.

laptop open). This method works in conjunction with handle_sleep() to allow Hyperspace to continue working after the machine on which it is running has been suspended and resumed, for example when the laptop is closed and then reopened. It extends all session leases by an amount computed as follows:

(now - m_sleep_time) + lease_interval
