Hello,
I have an action that triggers a very long running operation in a new thread
that continously dumps results to an IFile using the appendContents method.
The problem is that when this happens the whole project tree flashes and
refreshes, and it is 5 times slower than writing directly to a java.io.File.
Presumably this is because of the events that are triggered and the
corresponding listeners. Is there a mechanism for silently appending to a
file, or any other method that could stop the triggering of these events? I
don't notice any such effects when the java files are compiled to class
files by the jdt project, do they have some trick for doing this?
Thanks,
Tony

You can batch a set of changes to avoid resource change events using
IWorkspace.run(IWorkspaceRunnable). In Eclipse 3.0, you can also make
your background activity a subclass of WorkspaceJob. A WorkspaceJob
will batch its changes automatically. See
org.eclipse.core.runtime.jobs.Job, and
org.eclipse.core.resources.WorkspaceJob for more details.
