Michael, Thank you for taking the time to review this. I can see 1001 different ways to skin .... err bad metaphor for a cat logo framework. But the point is, I would like to get familiar with how to program with Kamaelia in a style the meshes with the least impedance.

Working through technical details is fine, but I want to learn the best style as well as just getting a working solution. > One very odd thing which jumps out at me though is this: > yield 1 > yield 1 > > Why the double yields ? Yes, that is indeed unusual. I was struggling a lot with getting components to shutdown when I tell them. The cascading conditionals is one result. A generic wrapper doesn't really know what message to send to make the child reliably shutdown. So I get progressively ruder in asking it to shutdown: producerFinished -> shutdownMicroprocess -> serverShutdown -> shutdown -> .stop(). After implementing this cascade, I thought I was still seeing cases where a component was reaching a rather rude level, shutdown, when a more polite producerShutdown should have been sufficient. I was looking at some of my own components and realized that I had cases where, upon receiving a message on "control", the component would perform a couple actions and yield once before performing final cleanup and exiting. So I posited that perhaps other components might need more than one bounce on the scheduler trampoline before they were able to stop cleanly. The simplest idea that came to mind was to yield two or three times after each increasingly urget shutdown message before the next check as to whether the child had indeed stopped. Basically I'm trying to get the child to shutdown in as gentle a manner as possible, but within bounded time (or cycles on the scheduler). I hope that makes sense. --Steve --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "kamaelia" group.
