Inheritance diagram for itk::ConditionalConstIterator< TImage >:

Detailed Description

template<typename TImage>
class itk::ConditionalConstIterator< TImage >

A base class for other iterators where membership in the set of output pixels is conditional upon some property, calculation, etc. For example, a threshold iterator might walk a region and return only those pixels which meet a minimum intensity condition.

This class is the const version of the ConditionalIterator. For this reason, it doesn't support the Set() method.

template<typename TImage >

constexpr unsigned int itk::ConditionalConstIterator< TImage >::NDimension = TImage::ImageDimension

static

Dimension of the image the iterator walks. This constant is needed so that functions that are templated over image iterator type (as opposed to being templated over pixel type and dimension) can have compile time access to the dimension of the image that the iterator walks.
