Detailed Description
The QContactMemoryEngine class provides an in-memory implementation of a contacts backend.
It may be used as a reference implementation, or when persistent storage is not required.
During construction, it will load the in-memory data associated with the memory store identified by the "id" parameter from the given parameters if it exists, or a new, anonymous store if it does not.
Data stored in this engine is only available in the current process.
This engine supports sharing, so an internal reference count is increased whenever a manager uses this backend, and is decreased when the manager no longer requires this engine.
Member Function Documentation
QContactMemoryEngine::QContactMemoryEngine ( QContactMemoryEngineData * data ) [protected]
Constructs a new in-memory backend which shares the given data with other shared memory engines.
QContactMemoryEngine::~QContactMemoryEngine ()
Frees any memory used by this engine
bool QContactMemoryEngine::cancelRequest ( QContactAbstractRequest * req ) [virtual]
Reimplemented from QContactManagerEngine::cancelRequest().
Reimplemented from QContactManagerEngine::contact().
Reimplemented from QContactManagerEngine::contacts().
QContactMemoryEngine * QContactMemoryEngine::createMemoryEngine ( const QMap<QString, QString> & parameters ) [static]
Factory function for creating a new in-memory backend, based on the given parameters.
The same engine will be returned for multiple calls with the same value for the "id" parameter, while one of them is in scope.
bool QContactMemoryEngine::hasFeature ( QContactManager::ManagerFeature feature, const QString & contactType ) const [virtual]
Reimplemented from QContactManagerEngine::hasFeature().
bool QContactMemoryEngine::isFilterSupported ( const QContactFilter & filter ) const [virtual]
Reimplemented from QContactManagerEngine::isFilterSupported().
The function returns true if the backend natively supports the given filter filter, otherwise false.
bool QContactMemoryEngine::isRelationshipTypeSupported ( const QString & relationshipType, const QString & contactType ) const [virtual]
Reimplemented from QContactManagerEngine::isRelationshipTypeSupported().
QString QContactMemoryEngine::managerName () const [virtual]
Reimplemented from QContactManagerEngine::managerName().
QMap<QString, QString> QContactMemoryEngine::managerParameters () const [virtual]
Reimplemented from QContactManagerEngine::managerParameters().
Reimplemented from QContactManagerEngine::relationships().
Reimplemented from QContactManagerEngine::removeContacts().
bool QContactMemoryEngine::removeDetailDefinition ( const QString & definitionId, const QString & contactType, QContactManager::Error * error ) [virtual]
Reimplemented from QContactManagerEngine::removeDetailDefinition().
Reimplemented from QContactManagerEngine::removeRelationships().
void QContactMemoryEngine::requestDestroyed ( QContactAbstractRequest * req ) [virtual]
Reimplemented from QContactManagerEngine::requestDestroyed().
Reimplemented from QContactManagerEngine::saveContacts().
Reimplemented from QContactManagerEngine::saveRelationships().
Reimplemented from QContactManagerEngine::selfContactId().
bool QContactMemoryEngine::startRequest ( QContactAbstractRequest * req ) [virtual]
Reimplemented from QContactManagerEngine::startRequest().
QList<QVariant::Type> QContactMemoryEngine::supportedDataTypes () const [virtual]
Reimplemented from QContactManagerEngine::supportedDataTypes().
bool QContactMemoryEngine::waitForRequestFinished ( QContactAbstractRequest * req, int msecs ) [virtual]
Reimplemented from QContactManagerEngine::waitForRequestFinished().
