Detailed Description

A progress reporter for concurrent threads.

Each thread should construct their own instance of the class. The ProcessObject::IncrementProgress method will be called to update the progress from all threads. The ProcessObject's method will automatically create ProgressEvents when the pipeline invoking thread updates the progress.

All threads concurrently contribute parts of the progress to the total number of pixels for all threads. This report will update the progress after a sufficient number of pixel to meet the numberOfUpdates requirement between all threads. Also when the object is deconstructed, all remaining pixels will increment the progress.

Constructor & Destructor Documentation

◆ TotalProgressReporter()

itk::TotalProgressReporter::TotalProgressReporter ( ProcessObject filter,
SizeValueType  totalNumberOfPixels,
SizeValueType  numberOfUpdates = 100,
float  progressWeight = 1.0f 

Construct a TotalProgressReporter.

filter- the ProcessObject which whose progress will be updated. If nullptr then no updates will occur.
totalNumberOfPixels- the number of pixels between all threads and chunks that will be updated. If zero, any completed chunk will result in a progress event.
numberOfUpdates- controls how often the ProcessObject's progress will be incremented
progressWeight- A percentage of the filters progress, this total number of pixels will contribute

◆ ~TotalProgressReporter()

itk::TotalProgressReporter::~TotalProgressReporter ( )

Destructor sets progress to 1 because the filter has finished.

Member Function Documentation

◆ CheckAbortGenerateData()

void itk::TotalProgressReporter::CheckAbortGenerateData ( )

Check if the filter has the ProcessObject::AbortGenerateData flag set. If true, then a ProcessAborted exception will be thrown.

◆ Completed()

void itk::TotalProgressReporter::Completed ( SizeValueType  count)

Called by a filter when a chunk, region, scan-line, etc. is completed.

Definition at line 102 of file itkTotalProgressReporter.h.

◆ CompletedPixel()

void itk::TotalProgressReporter::CompletedPixel ( )

Called by a filter once per pixel.
