[higgins-dev] [IdAS] IContextFactory.getContexts()
|
I'm still confused about the meaning of IContextFactory.getContexts().
The current wiki says: "return the set of Context References (URIs)
that are currently open and are managed by this provider".
So, a ContextFactory can: (a) keep a list of all created Context
instances, and (b) query each to see whether it's open or not. I can
see that, but when does a Context get deleted from this list? For a
long-running service, this could be a significant memory leak.
We could say that close() effectively removes it from the list. Then we
need to worry about what happens when a Context is closed twice. And we
either notify the ContextFactory of the close, or have the factory
remove it the next time it executes getContexts().
I know that my Use Case #5 has the user asking about which Contexts are
available. But I just added this because it's something we talked about
at some point. Is there a requirement for this? (Note: We can still
have "registered" Contexts that are advertised via the IdASRegistry.)
