Member Function Documentation

bool esve::components::dim4::Simple_Rotation_Handler::handle_check_awake (  bool   )  [protected, virtual]

Do you want to be awake? If currently awake, a return value of true indicates a desire to stay awake. If not currently awake, a return value of true indicates a desire to wake up. Implements esve::kernel::Wake_State_Handler.
