Hey Daklu,
Yeah it is probably possible. Right now I'm sipping my morning coffee and going over your Slave Loops concept. I feel that it's probably very similar to what I'm trying to do with my code but implemented in an OOP sense. Hopefully I can draw some parallels and a light will click. I'm particularly interested in the idea of launching and shutting down a slave process as needed.
I've gone through a really torturous route of wrapping each process inside a message handler framework, with an FGV pertinent to each process which is solely responsible for passing the stop message from the message handler to its process. The "process-nested-inside-message-handler" is in turn launced by a master message handler which handles input from the user to determine what tests should take place. I just had a blinding realisation as I wrote this that I could have handled this much simpler with a 0 time out queue in each process that listened for a stop message and if timed out did whatever the process was trying to do. One of the key assumptions that led me down my torturous path was that I must have a default case that handles messages which don't correspond to real messages.
*Realisation* In fact, I could just use the timeout line on the queue to nest another case structure and still handle the default (incorrect message) case, gah, so much time wasted.
From looking at your slave loops template posted in
this thread, am I right in assuming that if you wanted a different slave behaviour (a new plug in if you will), that you would merely make a new execute method in the SlaveLoop class? Or would you instantiate a whole new child class of SlaveLoop.lvclass with its own execute method?
Following on from my confession of my own wrangling efforts, how would you formulate one of your slave loops that needed to be a continuous process but also accept stop commands, would you use the timeout method I thought of above, or something else?
What would you do if you wanted to be able to close and reopen your slave loop without locking your code up? What I'm getting at here is, what is the OOP equivalent to launching a sub-vi using a property node with "Wait Until Done" set false?
Thank you for the opportunity to pick your brains! Your posts are always amazingly informative, even if it does take me months for things to finally click into place...
