Definition at line 336 of file asistreamhandler.cpp.

Referenced by Open(), Return(), and run().

◆ run()

void ASIStreamHandler::run ( void  )
overrideprivatevirtual

Runs the Qt event loop unless we have a QRunnable, in which case we run the runnable run instead.

Note
If you override this method you must call RunProlog before you do any work and RunEpilog before you exit the run method.

Reimplemented from MThread.

Definition at line 131 of file asistreamhandler.cpp.

◆ PriorityEvent()

void ASIStreamHandler::PriorityEvent ( int  fd)
overrideprivatevirtual

Implements DeviceReaderCB.

Definition at line 345 of file asistreamhandler.cpp.

◆ SetRunningDesired()

void ASIStreamHandler::SetRunningDesired ( bool  desired)
overrideprivatevirtual

At minimum this sets _running_desired, this may also send signals to anything that might be blocking the run() loop.

Note
: The _start_stop_lock must be held when this is called.

Reimplemented from StreamHandler.

Definition at line 124 of file asistreamhandler.cpp.
