IRepositoryTransaction Interface
See Also
The Repository supports transactional processing. Repository methods that are reading data from the 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/Commit method invocations is permitted, but no actual nesting of transactions occurs.
When to Use
Use the Repository Transaction 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.
