.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
An object that behaves much like Scope::Guard, but hardcoded to do the
right thing with transactions in DBIx::Class.
.SH "METHODS"
.IX Header "METHODS"
.SS "new"
.IX Subsection "new"
Creating an instance of this class will start a new transaction (by
implicitly calling \*(L"txn_begin\*(R" in DBIx::Class::Storage. Expects a
DBIx::Class::Storage object as its only argument.
.SS "commit"
.IX Subsection "commit"
Commit the transaction, and stop guarding the scope. If this method is not
called and this object goes out of scope (e.g. an exception is thrown) then
the transaction is rolled back, via \*(L"txn_rollback\*(R" in DBIx::Class::Storage
.SH "SEE ALSO"
.IX Header "SEE ALSO"
