Detailed Description

Constructor & Destructor Documentation

◆ QFirebirdDriverPrivate()

QFirebirdDriverPrivate::QFirebirdDriverPrivate ( )
inline

Definition at line 41 of file qsql_firebird_driver_p.h.

◆ ~QFirebirdDriverPrivate()

QFirebirdDriverPrivate::~QFirebirdDriverPrivate ( )
inline

Definition at line 48 of file qsql_firebird_driver_p.h.

Member Function Documentation

◆ finishTransaction()

bool QFirebirdDriverPrivate::finishTransaction ( TxnEnd end)

Finish the active user transaction by committing or rolling back. On a failed commit/rollback the handle is released and the member cleared so no caller sees a stale pointer. Shared by commitTransaction()/ rollbackTransaction(), which differ only in the verb.

Definition at line 173 of file qsql_firebird.cpp.

◆ setError()

void QFirebirdDriverPrivate::setError ( const QString & msg,
QSqlError::ErrorType type,
const QString & code = {} )
inline

Definition at line 84 of file qsql_firebird_driver_p.h.

◆ setFbError()

void QFirebirdDriverPrivate::setFbError ( const QString & context,
QSqlError::ErrorType type = QSqlError::UnknownError )

Definition at line 164 of file qsql_firebird.cpp.

Member Data Documentation

◆ activeResults

QList<QFirebirdResultPrivate *> QFirebirdDriverPrivate::activeResults

Results created from this driver. Tracked so they can be neutralised if the driver object is destroyed while a QSqlQuery is still alive — see ~QFirebirdDriver and QFirebirdResultPrivate::cleanup().

Definition at line 82 of file qsql_firebird_driver_p.h.

◆ attMutex

std::mutex QFirebirdDriverPrivate::attMutex

Guards the iAtt lifecycle (published in open(), withdrawn in close()) against cancelQuery(), which reads and uses the attachment from a foreign thread. All other iAtt access is owner-thread-only.

Definition at line 64 of file qsql_firebird_driver_p.h.

◆ cacheScrollableResults

bool QFirebirdDriverPrivate::cacheScrollableResults = false

Opt-in (connection option FB_SCROLLABLE_CACHE=1): when set, scrollable (non-forward-only) SELECT results buffer their rows client-side as they are first read, so random seek()s become in-memory lookups instead of a server fetchAbsolute round-trip each. Trades memory for random-access speed; off by default to preserve the driver's low-memory streaming model.

Definition at line 73 of file qsql_firebird_driver_p.h.

◆ eventSubscriptions

QHash<QString, QFirebirdEventSubscription *> QFirebirdDriverPrivate::eventSubscriptions

Definition at line 75 of file qsql_firebird_driver_p.h.

◆ iAtt

Firebird::IAttachment* QFirebirdDriverPrivate::iAtt = nullptr

Definition at line 56 of file qsql_firebird_driver_p.h.

◆ iStatus

Firebird::IStatus* QFirebirdDriverPrivate::iStatus = nullptr

Definition at line 55 of file qsql_firebird_driver_p.h.

◆ iTrans

Firebird::ITransaction* QFirebirdDriverPrivate::iTrans = nullptr

Definition at line 57 of file qsql_firebird_driver_p.h.

◆ master

Firebird::IMaster* QFirebirdDriverPrivate::master = nullptr
