Power Management | |
For devices which have remote power management (e.g. from one of the PDUs) we implement a standard power state monitoring and management component for the FSM. This needs to be enabled in the derived app constructor. To stay enabled, m_powerDevice and m_powerChannel must be not empty strings after the configuration. These could be set in the derived app defaults. If power management is enabled, then while power is off, appLogic will not be called. Instead a parrallel set of virtual functions is called, onPowerOff (to allow apps to perform cleanup) and whilePowerOff (to allow apps to keep variables updated, etc). Note that these could merely call appLogic if desired. | |

The execute method implementing the standard main loop. Should not normally be overridden.
Performs final startup steps. That is:
Errors in the above steps will cause a process exit.
Then commences the main event loop. Conditions on entry to the main loop:
In the event loop, the power state is checked (if being managed). If power is off, then onPowerOff is called. If power is on, or power is not managed, appLogic is called. These methods are implemented in derived classes, and are called every m_loopPause interval.
If an error is returned by either onPowerOff or appLogic, or a signal is handled, then the shutdown is managed. This includes shutting down INDI, calling appShutdown, and unlocking the PID. The log thread will shutdown.

This method exists to facilitate logging the reason for a state change once, but not logging it on subsequent event loops. Returns the current value upon entry, but updates before returning so that the next call returns the incremented value. Example usage:
In this example, the log entry is made the first time the state changes. If there are no changes to a different state in the mean time, then when the event loop gets here again and decides it is not connected, the log entry will not be made.
