When you wish to save a resource, do you need to explicitly interact
with the VCM provider if it protects resources? For example, when
calling IFile.create() or IFile.setContents, do you need to add any
explicit calls to the VCM provider? Or do you need to do something when
you open a file for editing?
I have been using an EMF-generated editor, which falls over when I set
it against files which are under ClearCase control, unless I explicitly
check them out first. Other editors, such as the Java editor, can handle
automatic check out of the file when you start editing it.

Colin,
Yeah, the editor really should handle checking out files. When I was adding
the initial support for listening to resource changes in the generated
editors I was hoping to add support for this as well. But it seemed most
important to do this in the generator itself where I added code like this to
ensure that a generated file which needs to be changed will be checked out:
if (targetFile.isReadOnly() &&
targetFile.getWorkspace().validateEdit(new IFile [] {
targetFile }, new SubProgressMonitor(progressMonitor, 1)).isOK())
Then time ran out, so we still need to add this type of
check-out-on-first-change logic to the generated editors.

Then time ran out, so we still need to add this type of check-out-on-first-change
logic to the generated editors.
