IRepositoryTransaction Interface
See Also
Microsoft® Repository supports transactional processing. Repository methods that are reading data from Repository may be executed outside of a transaction, but methods that write data must be bracketed within a transaction. Only one transaction may be active at a time for each opened repository instance. Nesting of Begin or Commit method invocations is permitted, but no actual nesting of transactions occurs.
When to Use
Use the IRepositoryTransaction interface to begin, commit, or abort a repository transaction. You can also use this interface to retrieve the information about the transactional state of an opened repository instance, and to set transaction options.
