Detailed Description

Facilitates progress reporting for filters that wrap around multiple other filters.

This object allows a mini-pipeline filters to easily keep track of the progress performed by the internal filters. See DiscreteGaussianImageFilter.hxx for an implementation example.

Constructor & Destructor Documentation

◆ ProgressAccumulator()

itk::ProgressAccumulator::ProgressAccumulator ( )
protected
Deprecated:
Reset the progress accumulator. This method should not be necessary because this functionality is already present in the filter constructor.
Deprecated:
Reset the filter progress but keep the accumulated progress. This method is deprecated because the ProgressAccumulator now internally checks if a filter has been restarted and updates the accumulated progress automatically. This method also used to have the unfortunate side effect of forcing filters to rerun even if their parameters and input had not changed. This is because it called SetProgress(0) on the filters, which triggered a ModifiedTime and thus caused the filters to rerun. To avoid this behavior, the implementation of this method is now empty.

Member Function Documentation

◆ CreateAnother()

virtual::itk::LightObject::Pointer itk::ProgressAccumulator::CreateAnother ( ) const
virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

◆ GetAccumulatedProgress()

virtual float itk::ProgressAccumulator::GetAccumulatedProgress ( ) const
virtual

Get the total progress accumulated by this object

◆ GetMiniPipelineFilter()

virtual const ProcessObject* itk::ProgressAccumulator::GetMiniPipelineFilter ( ) const
virtual

◆ GetModifiableMiniPipelineFilter()

virtual ProcessObject* itk::ProgressAccumulator::GetModifiableMiniPipelineFilter ( )
virtual

Set the mini-pipeline filter

◆ GetNameOfClass()

virtual const char* itk::ProgressAccumulator::GetNameOfClass ( ) const
virtual

Runtime information support.

Reimplemented from itk::Object.

◆ New()

static Pointer itk::ProgressAccumulator::New ( )
static

Standard New method.

◆ PrintSelf()

void itk::ProgressAccumulator::PrintSelf ( std::ostream &  os,
Indent  indent 
) const
overrideprotectedvirtual

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::Object.

◆ RegisterInternalFilter()

void itk::ProgressAccumulator::RegisterInternalFilter ( GenericFilterType filter,
float  weight 
)

Register a filter with the progress accumulator and specify the fraction of the overall progress associated with this filter. The sum of the weights for all filters that are registered should be 1. However, if streaming is used, the weight should be divided by the number of streams because each stream will reset the filter after capturing its progress. For example, if the desired weight of a filter is 0.4, but it is streamed into 4 streams, the weight should be 0.1. The ProgressAccumulator will then ensure that each of the 4 runs of this filter will add 0.1 to the filter's progress.

◆ ReportProgress()

void itk::ProgressAccumulator::ReportProgress ( Object object,
const EventObject event 
)
private

A callback function that is called by the progressing filters

◆ SetMiniPipelineFilter()

virtual void itk::ProgressAccumulator::SetMiniPipelineFilter ( ProcessObject _arg)
virtual

Set the mini-pipeline filter

◆ UnregisterAllFilters()

void itk::ProgressAccumulator::UnregisterAllFilters ( )

Unregister all filters that have been registered with this object
