Public Slots

void process (const FacePipelineExtendedPackage::Ptr &package)
 TODO: investigate this method.
 
- Public Slots inherited from Digikam::WorkerObject
void deactivate (DeactivatingMode mode=FlushSignals)
 Quits execution of this worker object.
 
void schedule ()
 Starts execution of this worker object: The object is moved to a thread and an event loop started, so that queued signals will be received.
 

Signals

void processed (const FacePipelineExtendedPackage::Ptr &package)
 
- Signals inherited from Digikam::WorkerObject
void finished ()
 
void started ()
 

Public Member Functions

 TrainerWorker (FacePipeline::Private *const dd)
 
- Public Member Functions inherited from Digikam::WorkerObject
 WorkerObject ()
 Deriving from a worker object allows you to execute your slots in a thread.
 
bool connectAndSchedule (const QObject *sender, const char *signal, const char *method, Qt::ConnectionType type=Qt::AutoConnection) const
 You must normally call schedule() to ensure that the object is active when you send a signal with work data.
 
QThread::Priority priority () const
 
void setPriority (QThread::Priority priority)
 Sets the priority for this dynamic thread.
 
State state () const
 
void wait ()
 

Protected Member Functions

void aboutToDeactivate () override
 Called from deactivate(), typically from a different thread than the worker thread, possibly the UI thread.
 
- Protected Member Functions inherited from Digikam::WorkerObject
virtual void aboutToQuitLoop ()
 Called from within thread's event loop to quit processing.
 
void addRunnable (WorkerObjectRunnable *loop)
 
bool event (QEvent *e) override
 
void removeRunnable (WorkerObjectRunnable *loop)
 
void run ()
 
void setEventLoop (QEventLoop *loop)
 
void shutDown ()
 If you are deleting data in your destructor which is accessed from the thread, do one of the following from your destructor to guarantee a safe shutdown: 1) Call this method 2) Call stop() and wait(), knowing that nothing will call start() anymore after this 3) Be sure the thread will never be running at destruction.
 
void transitionToInactive ()
 
bool transitionToRunning ()

◆ aboutToDeactivate()

void Digikam::TrainerWorker::aboutToDeactivate ( )
overrideprotectedvirtual

You can stop any extra controlled threads here. Immediately afterwards, an event will be sent to the working thread which will cause the event loop to quit. (aboutToQuitLoop())

Reimplemented from Digikam::WorkerObject.
