Add isStarted() to o.a.t.sca.assembly.Component?
For TUSCANY-1379 it seems easy enough to start or stop a component but there doesn't seem to be any way to find if the current state of a Component is started or stopped. Not sure if thats by design or not, what would people think about adding an isStarted method to the Component interface? ...ant

Hi, RuntimeComponent instead of Component is probably better to hold the state. We might be able to reuse "org.apache.tuscany.sca.scope.Lifecycle.java" (move to a different package) and have "org.apache.tuscany.sca.runtime.RuntimeComponent.java" extend from it. This way, the management interface can find the corresponding RuntimeComponent and then control the lifecycle of a componenent.

Ok, RuntimeComponent sounds good to me. I guess I wonder if extending the Lifecycle interface isn't over kill and then this would need to track all those intermediate states which i wonder if anyone is really interested in? The main reason I'm asking explicitly is these are interfaces we've said are in the stable SPI, so whats our policy on adding new methods? ...ant On 7/17/07, Raymond Feng <[EMAIL PROTECTED]> wrote: Hi, RuntimeComponent instead of Component is probably better to hold the state.

Seems ok to me since we will only be extending and not disrupting what exists already. And extending too seems ok since we are adding in a substantial feature here - support for management functions. - Venkat On 7/17/07, ant elder <[EMAIL PROTECTED]> wrote: Ok, RuntimeComponent sounds good to me.
