[news.eclipse.newcomer] Forcing a file to be un-savable

["Ben" <chibacity@xxxxxxxxx>]

Hi all,

I'm creating a derived IFile and having it opened in an editor. It gets 
programatically modified (and marked dirty) but the contents are not needed 
when the editor window is closed. I would like to prevent this file from 
being saved, and indeed don't want to be prompted with the "should I save" 
question.

Any ideas on how to achieve this?

Thanks.
