Member Function Documentation
QGeoSatelliteInfo::QGeoSatelliteInfo(const QGeoSatelliteInfo &other)
Creates a satellite information object with the values of other.
QGeoSatelliteInfo::QGeoSatelliteInfo()
Creates a satellite information object.
QGeoSatelliteInfo &QGeoSatelliteInfo::operator=(const QGeoSatelliteInfo &other)
Assigns the values from other to this object.
QGeoSatelliteInfo::~QGeoSatelliteInfo()
Destroys a satellite information object.
qreal QGeoSatelliteInfo::attribute(QGeoSatelliteInfo::Attribute attribute) const
Returns the value of the specified attribute as a qreal value.
Returns -1 if the value has not been set.
See also hasAttribute() and setAttribute().
bool QGeoSatelliteInfo::hasAttribute(QGeoSatelliteInfo::Attribute attribute) const
Returns true if the specified attribute is present in this update.
void QGeoSatelliteInfo::removeAttribute(QGeoSatelliteInfo::Attribute attribute)
Removes the specified attribute and its value.
int QGeoSatelliteInfo::satelliteIdentifier() const
Returns the satellite identifier number.
The satellite identifier number can be used to identify a satellite inside the satellite system. For satellite system GPS the satellite identifier number represents the PRN (Pseudo-random noise) number. For satellite system GLONASS the satellite identifier number represents the slot number.
See also setSatelliteIdentifier().
QGeoSatelliteInfo::SatelliteSystem QGeoSatelliteInfo::satelliteSystem() const
Returns the Satellite System (GPS, GLONASS, ...)
See also setSatelliteSystem().
void QGeoSatelliteInfo::setAttribute(QGeoSatelliteInfo::Attribute attribute, qreal value)
Sets the value for attribute to value.
See also attribute().
void QGeoSatelliteInfo::setSatelliteIdentifier(int satId)
Sets the satellite identifier number to satId.
The satellite identifier number can be used to identify a satellite inside the satellite system. For satellite system GPS the satellite identifier number represents the PRN (Pseudo-random noise) number. For satellite system GLONASS the satellite identifier number represents the slot number.
See also satelliteIdentifier().
void QGeoSatelliteInfo::setSatelliteSystem(QGeoSatelliteInfo::SatelliteSystem system)
Sets the Satellite System (GPS, GLONASS, ...) to system.
See also satelliteSystem().
void QGeoSatelliteInfo::setSignalStrength(int signalStrength)
Sets the signal strength to signalStrength, in decibels.
See also signalStrength().
int QGeoSatelliteInfo::signalStrength() const
Returns the signal strength, or -1 if the value has not been set.
See also setSignalStrength().
bool QGeoSatelliteInfo::operator!=(const QGeoSatelliteInfo &other) const
Returns true if any of the information for this satellite are not the same as those of other.
bool QGeoSatelliteInfo::operator==(const QGeoSatelliteInfo &other) const
Returns true if all the information for this satellite are the same as those of other.
