Public Member Functions

 USBDeviceThread (const char *name)
 
void run ()
 Main execution loop is defined here.
 
void preRun ()
 Called before entering the main execution loop, but after creating the thread.
 
void postRun ()
 Called after the main execution loop exits, but before joining the thread.
 
void sendSignal (USBDeviceSignalContext signal_ctx)
 Insert a signal into the signal_fifo.
 
void playCameraStreamCall (USBCameraConnectionContext ctx)
 
void stopCameraStreamCall (USBCameraConnectionContext ctx)
 
void requestStopCall ()
 API method: stops the thread. More...
 
- Public Member Functions inherited from Thread
 Thread (const char *name)
 Default constructor. More...
 
 ~Thread ()
 Destructor:not virtual. More...
 
virtual void preJoin ()
 Called before the thread is joined.
 
virtual void postJoin ()
 Called after the thread has been joined.
 
virtual void sendSignal (SignalContext signal_ctx)
 Send a signal to the thread.
 
virtual void sendSignalAndWait (SignalContext signal_ctx)
 Send a signal to the thread and wait for all signals to be executed.
 
void setAffinity (int i)
 API method for setting the thread affinity. More...
 
void startCall ()
 API method: starts the thread.
 
virtual void stopCall ()

Protected Member Functions

void handleSignal (USBDeviceSignalContext &signal_ctx)
 Handle an individual signal. Signal can originate from the frame fifo or from the signal_fifo deque.
 
void handleSignals ()
 Call USBDeviceThread::handleSignal for every signal in the signal_fifo.
 
void playCameraStream (USBCameraConnectionContext &ctx)
 
void stopCameraStream (USBCameraConnectionContext &ctx)
 
- Protected Member Functions inherited from Thread
void mainRun ()
 Does the preRun, run, postRun sequence.
 
void closeThread ()
 Sends exit signal to the thread, calls join. This method blocks until thread has exited. Set Thread::has_thread to false.

◆ requestStopCall()

void USBDeviceThread::requestStopCall ( )
virtual

API method: stops the thread.

Like Thread::stopCall() but does not block. Waiting for the thread to join is done in Thread::waitStoppedCall()

Reimplemented from Thread.
