Re: [udig-devel] Help with simple plugin

[Adrian Custer <acuster@xxxxxxxxx>]

Yeah, that's what the memory data store is for. As long as you don't
have a gazillion features, it's very useful. Also there's now a trigger
to save the in memory contents prior to exit.

now *how* to go about doing all this is another issue. I'm currently
debugging something similar so my code can't yet serve as a useful
example to you.
