TransactionSingleOpOperation
Operation.setResult(OtpErlangObject, boolean)
assuming that operation was committed.
In contrast to Operation.processResult()
operations like WriteOp
will throw a proper AbortException
for their commit part instead
of an UnknownException
.
Note: the created value is not cached!

in interface TransactionSingleOpOperation
AbortException
- if a commit failed
