def stageShutdown(): Unit

Shuts down the stage, deallocating resources, etc.
Shuts down the stage, deallocating resources, etc.
This method will be called when the stages receives a Disconnected command unless the inboundCommand method is overridden. It is not impossible that this will not be called due to failure for other stages to propagate shutdown commands. Conversely, it is also possible for this to be called more than once due to the reception of multiple disconnect commands. It is therefor recommended that the method be idempotent.

def stageStartup(): Unit

Start the stage, allocating resources etc.
This method should not effect other stages by sending commands etc unless it creates them. It is not impossible that the stage will receive other commands besides Connected before this method is called. It is not impossible for this method to be called multiple times by misbehaving stages. It is therefor recommended that the method be idempotent.
