Member Function Documentation

QGeoSatelliteInfo::QGeoSatelliteInfo()

Creates a satellite information object.

QGeoSatelliteInfo::QGeoSatelliteInfo(const QGeoSatelliteInfo &other)

Creates a satellite information object with the values of other.

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.

QGeoSatelliteInfo &QGeoSatelliteInfo::operator=(const QGeoSatelliteInfo &other)

Assigns the values from other to this object.

bool QGeoSatelliteInfo::operator==(const QGeoSatelliteInfo &other) const

Returns true if all the information for this satellite are the same as those of other.
