Commits a transaction

final public void MongoDB\Driver\Session::commitTransaction ( void )

This method commits an existing transaction and all the associated operations are persisted in the database.

This function has no parameters.

No value is returned.

Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
Throws MongoDB\Driver\Exception\CommandException if the server could not commit the transaction (e.g. due to conflicts, network issues). In case the exception's MongoDB\Driver\Exception\CommandException::getResultDocument() has a "errorLabels" element, and this array contains a "TransientTransactionError" or "UnUnknownTransactionCommitResult" value, it is safe to re-try the whole transaction. In newer versions of the driver, MongoDB\Driver\Exception\RuntimeException::hasErrorLabel() should be used to test for this situation instead.
Throws MongoDB\Driver\Exception\RuntimeException if the transaction could not be commited (e.g. a transaction was not started).
