Detailed Description

template<class TPixel, class 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.

Member Function Documentation

template<class TPixel, class TContainer>
ConstSliceIterator itk::ConstSliceIterator< TPixel, TContainer >::Begin   [inline]
 

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

Definition at line 57 of file itkConstSliceIterator.h.

References itk::ConstSliceIterator< TPixel, TContainer >::m_Pos.

template<class TPixel, class TContainer>
ConstSliceIterator itk::ConstSliceIterator< TPixel, TContainer >::End   [inline]
 

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

Definition at line 65 of file itkConstSliceIterator.h.

References itk::ConstSliceIterator< TPixel, TContainer >::m_Pos.

template<class TPixel, class TContainer>
const TPixel& itk::ConstSliceIterator< TPixel, TContainer >::operator *   [inline]
 

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

Definition at line 97 of file itkConstSliceIterator.h.

template<class TPixel, class TContainer>
bool itk::ConstSliceIterator< TPixel, TContainer >::operator!= const ConstSliceIterator< TPixel, TContainer > &    orig [inline]
 

Returns the logical inverse of the boolean == of two slice iterators.

Definition at line 112 of file itkConstSliceIterator.h.

template<class TPixel, class TContainer>
ConstSliceIterator itk::ConstSliceIterator< TPixel, TContainer >::operator++ int    [inline]
 

Increments the iterator.

Definition at line 81 of file itkConstSliceIterator.h.

template<class TPixel, class TContainer>
ConstSliceIterator itk::ConstSliceIterator< TPixel, TContainer >::operator++   [inline]
 

Increments the iterator.

Definition at line 74 of file itkConstSliceIterator.h.

template<class TPixel, class TContainer>
bool itk::ConstSliceIterator< TPixel, TContainer >::operator< const ConstSliceIterator< TPixel, TContainer > &    orig [inline]
 

Returns the boolean < of two slice iterator positions. Result is only true if the slice iterators have the same stride and start location.

Definition at line 120 of file itkConstSliceIterator.h.

template<class TPixel, class TContainer>
bool itk::ConstSliceIterator< TPixel, TContainer >::operator== const ConstSliceIterator< TPixel, TContainer > &    orig [inline]
 

Returns the logical && of the boolean == of two slice iterator positions, stride, and start locations.

Definition at line 104 of file itkConstSliceIterator.h.

template<class TPixel, class TContainer>
const TPixel& itk::ConstSliceIterator< TPixel, TContainer >::operator[] unsigned long    n [inline]
 

Returns the element at position n of the slice. Sets the iterator to point to position n.
