Log Activity and Write Telemetry in Constructor

[MichaelStarks]

I have a State Machine object and would like to log the state telemetry and activity in the constructor. When I move the this->log_ACTIVITY_HI_STATE_CHANGE(); and this->tlmWrite_STATE(); to the constructor I fail the unit test that I have written. When I remove the portion of the unit test that checks the start-up state it passes, from this I assume the activity and telemetry are either not being logged or are being cleared. How should I setup setting the start-up state so that the information is logged?

Thank you

I wanted to follow up on this question -- is there any way to log in the constructor of a component?

F Prime's logging and telemetry handling is not guaranteed to be initialized at the time of component construction. Because they are themselves components, this would be a race condition. For those mechanisms to work, the topology ports need to be connected; a process that starts after all of the component instances have been constructed and initialized. BTW; that also means you won't have access to spacecraft time via getTime() either.

So, if you want to log something during construction for debugging and testing purposes, you could go around the built-in tooling and just printf() that information. If you need that information to go through a flight or flight-like downlink to a GDS, you will have to cache that information somewhere like member variables and downlink it at a later time.
