Detailed Description

Manages sensors.

QgsSensorManager handles the storage, serializing and deserializing of sensors. Usually this class is not constructed directly, but rather accessed through a QgsProject via QgsProject::sensorManager().

Since
QGIS 3.32

Constructor & Destructor Documentation

◆ QgsSensorManager()

QgsSensorManager::QgsSensorManager ( QObject *  parent = nullptr)
explicit

Constructor for QgsSensorManager, with the specified parent object.

Definition at line 21 of file qgssensormanager.cpp.

◆ ~QgsSensorManager()

QgsSensorManager::~QgsSensorManager ( )
override

Definition at line 26 of file qgssensormanager.cpp.

Member Function Documentation

◆ addSensor()

void QgsSensorManager::addSensor ( QgsAbstractSensor sensor)

Registers a new sensor.

The sensor name does not require uniqueness; sensors will the same name will store their data in the same sensor name key, allowing for registration of sensors to cover multiple devices (e.g. two serial port sensors with alternative port name to cover two machines).

Note
Takes ownership of the sensor.

Definition at line 83 of file qgssensormanager.cpp.

◆ clear()

void QgsSensorManager::clear ( )

Deregisters and removes all sensors from the manager.

Definition at line 31 of file qgssensormanager.cpp.

◆ readXml()

bool QgsSensorManager::readXml ( const QDomElement &  element,
const QDomDocument &  document 
)

Reads the manager's state from a DOM element, restoring all sensors present in the XML document.

writeXml()

Definition at line 160 of file qgssensormanager.cpp.

◆ removeSensor()

bool QgsSensorManager::removeSensor ( const QString &  id)

Removes a registered sensor matching a given id.

Returns
true if a sensor was removed.

Definition at line 99 of file qgssensormanager.cpp.

◆ sensor()

QgsAbstractSensor * QgsSensorManager::sensor ( const QString &  id) const

Returns a registered sensor pointer matching a given id.

If not matching sensor is found, a nullptr will be returned.

◆ sensorAboutToBeRemoved

void QgsSensorManager::sensorAboutToBeRemoved ( const QString &  id)
signal

Emitted when a sensor is about to be removed.

◆ sensorAdded

void QgsSensorManager::sensorAdded ( const QString &  id)
signal

Emitted when a sensor has been registered.

◆ sensorData()

QgsAbstractSensor::SensorData QgsSensorManager::sensorData ( const QString &  name) const

Returns the last captured data from a registered sensor matching a given name.

Definition at line 63 of file qgssensormanager.cpp.

◆ sensorDataCaptured

void QgsSensorManager::sensorDataCaptured ( const QString &  id)
signal

Emitted when newly captured data from a sensor has occurred.

◆ sensorErrorOccurred

void QgsSensorManager::sensorErrorOccurred ( const QString &  id)
signal

Emitted when a sensor error has occurred.

◆ sensorNameChanged

void QgsSensorManager::sensorNameChanged ( const QString &  id)
signal

Emitted when a sensor name has changed.

◆ sensorNames()

QStringList QgsSensorManager::sensorNames ( ) const

Returns a list of registered sensor names.

Definition at line 73 of file qgssensormanager.cpp.

◆ sensorRemoved

void QgsSensorManager::sensorRemoved ( const QString &  id)
signal

Emitted when a sensor has been removed.

◆ sensors()

QList< QgsAbstractSensor * > QgsSensorManager::sensors ( ) const

Returns a list of pointers to all registered sensors.

Definition at line 45 of file qgssensormanager.cpp.

◆ sensorsData()

QMap< QString, QgsAbstractSensor::SensorData > QgsSensorManager::sensorsData ( ) const

Returns the last captured data of all registered sensors.

Definition at line 68 of file qgssensormanager.cpp.

◆ sensorStatusChanged

void QgsSensorManager::sensorStatusChanged ( const QString &  id)
signal

Emitted when a sensor status has changed.
