uDig has a commit / rollback workflow. So you can edit, perform operations and so on, and when you are happy with the result press the commit button. For databases any information you modified is handled by a database transaction; for a shapefile any changes are held in memory (only the changes not the whole shapefile) until you press commit.
For more information please see walkthrough 2. Since you are on the devel list; the GeoTools library does support working in "AUTO-COMMIT" mode - we just don't make use of that from uDig.
