Constructor & Destructor Documentation
◆ Transaction()
|
explicit |
Starts a new transaction.
The transaction will automatically rolled back on destruction if it hasn't been committed explicitly before. If there is already a global transaction in progress, this one will be used instead of creating a new one.
- Parameters
-
db The corresponding DataStore. You must not delete db
during the lifetime of a Transaction object.name A name of the transaction. Used for debugging. beginTransaction if false, the transaction won't be started, until begin is explicitly called. The default is to begin the transaction right away.
Definition at line 12 of file transaction.cpp.
◆ ~Transaction()
Transaction::~Transaction | ( | ) |
Rolls back the transaction if it hasn't been committed explicitly.
This also happens if a global transaction is used.
Definition at line 22 of file transaction.cpp.

void Transaction::begin | ( | ) |
Definition at line 35 of file transaction.cpp.
◆ commit()
bool Transaction::commit | ( | ) |
