The Transaction class provides the capability of interacting directly with a transaction performing a number of database operations.
As explained in the Managing eXtremeSQL Transactions in C++ page, it is possible to manage a block of database transactions by calling the McoSqlEngine method beginTransaction() to create a Transaction object. The Transaction class provides the following methods:
| commit(int phase) | Commit the block of database operations performed in this transaction |
| checkpoint() | Checkpoint this transaction which updates indexes and makes newly inserted objects visible to queries while the transaction is still open |
| rollback() | Roll back the database changes performed in this transaction |
| release() | Release the memory objects associated with this transaction |
