Chapter 4 Updating a Snapshot View

The rules in your view's config spec are usually designed to select a discrete set of versions from the VOB. For example, your view is usually intended to contain a set of versions that build successfully. However, when other developers check in new versions from their views, a snapshot view may become out of date or inconsistent with the versions in the VOB. To make sure that your view contains the set of versions the config spec selects, you must update it.

This chapter explains

• Starting an update operation

• What happens when you update a view

• Unloading elements

An update operation copies versions of elements from a VOB to your view. Only the checkin operation copies changes from your view back to a VOB.
