\brief The QIfAmFmTunerBackendInterface defines the interface for backends to the
QIfAmFmTuner feature class.
The QIfAmFmTunerBackendInterface is the interface used by \l QIfAmFmTuner
The interface is discovered by a \l QIfAmFmTuner object, which connects to it and sets it up.
<example of a fully featured backend>
*/
/*!
Constructs a backend interface.
The \a parent is sent to the QObject constructor.

/*!
\fn QIfAmFmTunerBackendInterface::setFrequency(int frequency)
Changes the frequency to the new value passed as \a frequency.
This method is expected to emit a \l frequencyChanged() signal when the internal state changes due to this function call
*/
/*!
\fn QIfAmFmTunerBackendInterface::setBand(QIfAmFmTuner::Band band)
Changes the band to the new value passed as \a band.

Increases the frequency by the current bands step size.

Decreases the frequency by the current bands step size.

\fn QIfAmFmTunerBackendInterface::startScan()
Starts a scan through all available stations.
The scan will seek to the next available station and will stay there for some seconds until it seeks to the next station.
It is expected that this function will inform about the current state of the backend by emitting the scanStatusChanged() signal.
\sa stopScan() scanStatusChanged()
*/
/*!
\fn QIfAmFmTunerBackendInterface::stopScan()
Stops the currently active scan. If no scan is active, this method does nothing.
It is expected that this function will inform about the current state of the backend by emitting the scanStatusChanged() signal.

/*!
\fn QIfAmFmTunerBackendInterface::frequencyChanged(int frequency)
Emitted when the current frequency changed. The new value is passed as \a frequency.

\fn QIfAmFmTunerBackendInterface::minimumFrequencyChanged(int minimumFrequency)
Emitted when the minimum frequency of the current band changed. The new value is passed as \a minimumFrequency.
This is usually caused by a switching the band.

*/
/*!
\fn QIfAmFmTunerBackendInterface::maximumFrequencyChanged(int maximumFrequency)
Emitted when the maximum frequency of the current band changed. The new value is passed as \a maximumFrequency.

Emitted when the current station changed. The new station is passed as \a station.

\fn QIfAmFmTunerBackendInterface::scanStatusChanged(bool scanRunning)
Emitted when the status of the station scan has changed. This signal should be emitted
as a result of a call to startScan() or stopScan() and informs about the current status using the \a scanRunning argument.
