<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">MyMoneyFile::addTransaction() requires a reference to MyMoneyTransaction, not a const reference which is available in MyMoneyStatementReader::addTransaction(). This is due to the fact, that the transaction is modified in MyMoneyFile::addTransaction() just before it is stored.
The instance of the MyMoneyTransaction is not used after passing it to MyMoneyFile::addTransaction(), so passing a copy (which then gets modified there) should not hurt. However this is not the best solution possible - I admit that. Further refactoring is desired, but I don't want to make this review even bigger.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I thought so, that's why I asked the question. I this case I would change MyMoneyStatementReader::addTransaction(const MyMoneyTransaction& transaction) to MyMoneyStatementReader::addTransaction(MyMoneyTransaction& transaction) and remove the copying. That way if someone will think of using the transaction object in the future after it was added it will be in a correct state. I think it's more correct this way in the current state of the patch.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">1. please note that dependency on Boost is no longer optional (see changes in CMakeLists.txt)
2. Architectural changes
Until now, the method MyMoneyStatementReader::processTransactionEntry() handled the whole process of importing a transaction - that is: handling the securities, matching and creating payees, and - at the very end of the method - adding the transaction to the ledger.
The last step (adding transaction to ledger) is the main target of this refactoring. Its algorithm was as follows:
1. find a matching transaction (either existing or scheduled) - using TransactionMatcher::findMatch()
2. If an "existing transaction match" is found - handle it (in the old code it's the block starting with a comment "// it matched a simple transaction. that's the easy case")
3. Else if a "scheduled transaction match" is found - handle it ("// a match has been found in a pending schedule"...)
Code "mapping" is as follows:
- step 2 (above) is extracted to handleMatchingOfExistingTransaction()
- step 3 (above) is extracted to handleMatchingOfScheduledTransaction()
- TransactionMatcher::findMatch() is extracted to TransactionMatchFinder::findMatch() (note: there are two pure-virtual functions that are implemented in ExistingTransactionMatchFinder, ScheduledTransactionMatchFinder classes)
- TransactionMatcher::checkTransaction() is extracted to TransactionMatchFinder::findMatchingSplit()
3. Memory management changes
Raw pointers are no longer used, as these are typically error-prone. Pointers were replaced either with object instances, or boost::optional is used if applicable (e.g. see members of TransactionMatchFinder class).
4. dynamic_casts removed (were used on pointers returned by TransactionMatcher::findMatch(), no longer needed - see TransactionMatchFinder::getMatchedTransaction() and getMatchedSchedule() )
5. variable/method names - I did my best to keep those meaningful: e.g. "importedTransaction" instead of "t")
