The XmlTransaction class is the handle for a transaction. It encapsulates a DB_TXN handle. Methods of the XmlTransaction class are used to abort and commit the transaction. XmlTransaction handles are provided to XmlContainer , XmlManager , and other objects that query and modify documents and containers in order to transactionally protect those database operations.

XmlTransaction objects are instantiated using XmlManager::createTransaction.

XmlTransaction handles are not free-threaded; transactions handles may be used by multiple threads, but only serially, that is, the application must serialize access to the XmlTransaction handle. Once the XmlTransaction::abort or XmlTransaction::commit methods are called, the handle may not be accessed again, regardless of the method's return. In addition, parent transactions may not issue any operations while they have active child transactions (child transactions that have not yet been committed or aborted) except for XmlTransaction::abort and XmlTransaction::commit.

If the object is used after a commit or abort, an exception is thrown with the exception code, TRANSACTION_ERROR.
