itk::ConstSliceIterator< TPixel, TContainer > Class Template Reference

#include <itkConstSliceIterator.h>

Detailed Description

template<typename TPixel, typename TContainer>
class itk::ConstSliceIterator< TPixel, TContainer >

A flexible iterator for ITK containers(i.e. itk::Neighborhood) that support pixel access through operator[].

ConstSliceIterator allows const iteration along a std::slice through the container. A slice is a construct that defines a starting position, stride length (distance between adjacent elements), and a length.

Any container with operator[] const is supported. Because it uses this interface the iterator is only as efficient as the implementation of a container's operator[] method.

References: Modeled after a slice iterator proposed by Bjarne Stroustrup in [111].

Begin()

template<typename TPixel, typename TContainer>

ConstSliceIterator itk::ConstSliceIterator< TPixel, TContainer >::Begin ( )

inline

Returns a ConstSliceIterator that points to the beginning of the slice.

End()

template<typename TPixel, typename TContainer>

ConstSliceIterator itk::ConstSliceIterator< TPixel, TContainer >::End ( )

inline

Returns a ConstSliceIterator that points to one past the end of the slice.

operator*()

template<typename TPixel, typename TContainer>

const TPixel & itk::ConstSliceIterator< TPixel, TContainer >::operator* ( )

inline

Dereferences the iterator, returning the value that it points to.

operator++() [1/2]

template<typename TPixel, typename TContainer>

ConstSliceIterator itk::ConstSliceIterator< TPixel, TContainer >::operator++ ( )

inline

Increments the iterator.

operator++() [2/2]

template<typename TPixel, typename TContainer>

ConstSliceIterator itk::ConstSliceIterator< TPixel, TContainer >::operator++ ( int )

inline

Increments the iterator.
