IRepositoryTransaction Interface
The repository engine supports transactional processing. Repository engine methods that are reading data from a repository database may be executed outside of a transaction, but methods that write data must be bracketed within a transaction. Only one transaction can 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 cancel a repository transaction. You can also use this interface to retrieve the information about the transactional state of an open repository instance, and to set transaction options.
