Chapter 9. Resource Change Tracking
The Eclipse system generates resource change events indicating, for example, the files and folders that have been added, modified, and removed during the course of an operation. Interested objects can subscribe to these events and take whatever action is necessary to keep themselves synchronized with Eclipse.
To demonstrate resource change tracking, the Favorites view will be modified (see Chapter 7, Views) so that whenever a resource is deleted, you can remove the corresponding element from the Favorites view.
