Hi Jeff,
I suppose that we can build communication between checker and Eclipse by
using sockets. But, you know, it's not the best (though) solution.
The other way to orginize communication is (I HAVEN'T CHECKED IT!!!!
TRY!!! IT SHOULD WORK!!!):
1. Register your view as DebugEventListener
(see org.eclipse.debug.core.DebugPlugin docs)
Using this listener you'll be able to get source object that
describes running application. You are interested in IProcess objects.
(org.eclipse.debug.core.model.IProcess)
2. You can add output/error stream listeners to this IProcess
(smth like
IProcess.getStreamsProxy().getOutputStreamMonitor().addListener(IStreamListener
listener) )
3. In your checker print lines in some format, so you can understand in
your plugin what line is being printed to the stream by checker.
4. To find out what (running) project actually complaining you need to
extend format of messages with the name of the project. You can do it by
rewriting checker code on copying, just like you do with GlobalPreffered
or Stable pointcuts. SO, your checker will complain errors, that contains
project name, plugin intercepts those messages, decides, whether it should
be reflected in the view or not etc.
As you can understand, this way is not trivial, but I suspect it's the
best one.
To find out more about views / Viewer models just take a look at the
http://www.ccs.neu.edu/home/lieber/com3205/f02/eclipse/src/
folder. It contains an example I presented in the class.
I believe, it's helpful.
Good luck,
Sergei.
