In the current specification, it is fairly straightforward to implement an Avalon container. When would you suggest the container poll this new isRunning method? It would be preferable to have the component notify the container if it shut itself down. However, then you run the risk of perverting IOC.
The Startable interface is simply a lifecycle interface that stipulates a contract with the container. The container does not really care what the start() and stop() methods actually do -- or even what they start or stop. The contract is simple, and I am opposed to complicating it. Components are given the resources to manage themselves (that is the point). ----- Original Message ----- From: "Yannick Menager" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, October 08, 2003 1:22 PM Subject: Re: Startable doesn't has a isRunning() interface ? > But that way you're putting a risk that the container might be out of > sync with the real state of the component.
