Behavior of IWorkspace.run() [message #264474]

I want to know that when we run some actions that make changes to the work
space, but in the IWorkspaceRunnable.run() method that we pass onto
Workspace.run(). Then, how does the workspace comes to know that what
changes have been made to the workspace.

For example i run a tool that creates a zip file of some of the resources i
put this action in this run method but when the method returns the workspace
doesnt show the zip file in the navigatro view. Althought it is there in the
file system. It appears if i refresh it. (I am using eclipse 2.1)

Do i need to perform some other tasks like create or modify the delta and
return it back or somehow hint the workspace as to what and where the change
has occured or does the workspace automatically detects all the changes once
the run has been called.

Please help me on this i am stuck at this and i have no idea what the
problem could be.

If you use the Eclipse methods to modify files (e.g.
IFile.setContents()) or modify folders (e.g. IFolder.create(...)) etc.,
then Eclipse knows immediately you changed something and you don't to
tell it so.

But if you go straight to the file system then Eclipse doesn't know you
did anything. You have to tell it you did something within the runnable
by doing an explicit refresh within the runnable. To programatically do
a refresh you must use IResource.refreshLocal(...) If you do this on a
folder and tell it to recurse by using a depth of
IResource.DEPTH_INFINITE it will walk through the folder and all
subfolders to see what files have been touched. It will then update its
own internal tables.

There is a pretty good discussion on this topic at

http://eclipsefaq.org, Chapter 17, Workspace and Resources API
FAQ 289 How can I be notified of changes to the workspace?
