Member Function Documentation

◆ calculate()

template<class T >
virtual T cx::ThreadedTimedAlgorithm< T >::calculate ( )
protectedpure virtual

This is the threaded function, should only contain threadsafe function calls.

◆ execute()

template<class T >
virtual void cx::ThreadedTimedAlgorithm< T >::execute ( )
inlinevirtual

Execute the algorithm. Parts of the execution can be in another thread, thus the call usually returns after preprocessing is complete. The exec starts by emitting aboutToStart(), which can be used by callers to set input arguments.

Implements cx::TimedBaseAlgorithm.

Reimplemented in cx::ConnectedThresholdImageFilter.

◆ generate()

template<class T >
void cx::ThreadedTimedAlgorithm< T >::generate ( )
inlineprotected

Definition at line 66 of file cxThreadedTimedAlgorithm.h.

◆ getResult() [1/3]

cxResource_EXPORT void cx::ThreadedTimedAlgorithm< void >::getResult ( )
protected

Definition at line 35 of file cxThreadedTimedAlgorithm.cpp.

◆ getResult() [2/3]

template<class T >
T cx::ThreadedTimedAlgorithm< T >::getResult ( )
inlineprotected

Definition at line 74 of file cxThreadedTimedAlgorithm.h.

◆ getResult() [3/3]

cxResource_EXPORT void cx::ThreadedTimedAlgorithm< void >::getResult ( )
protected

◆ isFinished()

template<class T >
virtual bool cx::ThreadedTimedAlgorithm< T >::isFinished ( ) const
inlinevirtual

Returns true after the finished() signal is emitted.

Implements cx::TimedBaseAlgorithm.

Definition at line 55 of file cxThreadedTimedAlgorithm.h.

◆ isRunning()

template<class T >
virtual bool cx::ThreadedTimedAlgorithm< T >::isRunning ( ) const
inlinevirtual

Returns true if preprocess is started and postprocess not complete. (Right after aboutToStart, right before finished())

Implements cx::TimedBaseAlgorithm.

Definition at line 56 of file cxThreadedTimedAlgorithm.h.

◆ postProcessingSlot()

template<class T >
virtual void cx::ThreadedTimedAlgorithm< T >::postProcessingSlot ( )
protectedpure virtual

This happens when the thread (calculate) is finished, here non-thread safe functions can be called.

Reimplemented from cx::TimedBaseAlgorithm.
