Detailed Description
The QLandmarkExportRequest class allows a client to asynchronously request that a landmark manager export a set of landmarks.
For a QLandmarkExportRequest, the QLandmarkAbstractRequest::stateChanged() signal will be emitted when the request is complete. The resultsAvailable() signal will be emitted if an overall operational error occurs.
If no landmarks identifiers are set using setLandmarkIds() or an empty list is passed in, then all the landmarks will be exported.
Please see the class documentation for QLandmarkAbstractRequest for more information about the usage of request classes and ownership semantics.
Member Function Documentation
QLandmarkExportRequest::QLandmarkExportRequest ( QLandmarkManager * manager, QObject * parent = 0 )
Constructs a landmark export request with the given manager and parent.
QLandmarkExportRequest::~QLandmarkExportRequest ()
Destroys the request object.
QIODevice * QLandmarkExportRequest::device () const
Returns the device to which landmarks are written.
See also setDevice().
QString QLandmarkExportRequest::fileName () const
If the currently assigned device is a QFile, or if setFileName() has been called, this function returns the name of the file to be written to. In all other cases, it returns an empty string.
See also setFileName() and setDevice().
QString QLandmarkExportRequest::format () const
Returns the data format for the export operation.
See also setFormat().
QList<QLandmarkId> QLandmarkExportRequest::landmarkIds () const
Returns the list of identifiers of landmarks that will be exported. By default the list of identifiers is empty, indicating that all landmarks should be exported.
See also setLandmarkIds().
void QLandmarkExportRequest::setDevice ( QIODevice * device )
Sets the device to which landmarks are written.
See also device().
void QLandmarkExportRequest::setFileName ( const QString & fileName )
Sets the name of the file to be written to fileName. Internally, QLandmarkExportRequest will create a QFile use this as the device to export to.
See also fileName() and setDevice().
void QLandmarkExportRequest::setFormat ( const QString & format )
Sets the data format for the export operation.
See also format().
void QLandmarkExportRequest::setLandmarkIds ( const QList<QLandmarkId> & landmarkIds )
Sets the landmarks to be exported by specifying a list of landmarkIds.
See also landmarkIds().
Sets the transfer option of the export request. The transfer option defines how categories are treated during the export operation.
See also transferOption().
Returns the transfer option of the export request. The transfer option defines how categories are treated during the export operation. The default option is QLandmarkManager::IncludeCategoryData.
See also setTransferOption().
