Detailed Description

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

Multi-dimensional image iterator.

ImageReverseConstIterator is a templated class to represent a multi-dimensional iterator. ImageReverseConstIterator is templated over the dimension of the image and the data type of the image.

ImageReverseConstIterator is a base class for all the reverse image iterators. It provides the basic construction and comparison operations. However, it does not provide mechanisms for moving the iterator. A subclass of ImageReverseConstIterator must be used to move the iterator.

ImageReverseConstIterator is a multi-dimensional iterator, requiring more information be specified before the iterator can be used than conventional iterators. Whereas the std::vector::iterator from the STL only needs to be passed a pointer to establish the iterator, the multi-dimensional image iterator needs a pointer, the size of the buffer, the size of the region, the start index of the buffer, and the start index of the region. To gain access to this information, ImageReverseConstIterator holds a reference to the image over which it is traversing.

ImageReverseConstIterator assumes a particular layout of the image data. In particular, the data is arranged in a 1D array as if it were [][][][slice][row][col] with Index[0] = col, Index[1] = row, Index[2] = slice, etc.

template<typename TImage>
itk::ImageReverseConstIterator< TImage >::ImageReverseConstIterator (  )  [inline]

Default Constructor. Need to provide a default constructor since we provide a copy constructor.

template<typename TImage>
virtual itk::ImageReverseConstIterator< TImage >::~ImageReverseConstIterator (  )  [inline, virtual]

Default Destructor.

Definition at line 150 of file itkImageReverseConstIterator.h.

template<typename TImage>
itk::ImageReverseConstIterator< TImage >::ImageReverseConstIterator ( const Self it  )  [inline]

Copy Constructor. The copy constructor is provided to make sure the handle to the image is properly reference counted.

template<typename TImage>
itk::ImageReverseConstIterator< TImage >::ImageReverseConstIterator ( ImageType ptr,
const RegionType region 
) [inline]

Constructor establishes an iterator to walk a particular image and a particular region of that image.

Definition at line 171 of file itkImageReverseConstIterator.h.

template<typename TImage>
itk::ImageReverseConstIterator< TImage >::ImageReverseConstIterator ( const ImageConstIterator< TImage > &  it  )  [inline]

Constructor that can be used to cast from an ImageConstIterator to an ImageRegionReverseIterator. Many routines return an ImageConstIterator but for a particular task, you may want an ImageRegionReverseIterator. Rather than provide overloaded APIs that return different types of Iterators, itk returns ImageConstIterators and uses constructors to cast from an ImageConstIterator to a ImageRegionReverseIterator.

template<typename TImage>
Self itk::ImageReverseConstIterator< TImage >::End (  )  const

Return an iterator for the end of the region. "End" for a reverse iterator is one pixel before the first pixel in the region.

Deprecated:
Use GoToEnd() instead

Reimplemented in itk::ImageRegionReverseConstIterator< TImage >, and itk::ImageRegionReverseIterator< TImage >.

template<typename TImage>
const PixelType itk::ImageReverseConstIterator< TImage >::Get ( void   )  const [inline]

template<typename TImage>
static unsigned int itk::ImageReverseConstIterator< TImage >::GetImageIteratorDimension (  )  [inline, static]

Definition at line 283 of file itkImageReverseConstIterator.h.

template<typename TImage>
const IndexType itk::ImageReverseConstIterator< TImage >::GetIndex ( void   )  [inline]

Get the index. This provides a read only reference to the index. This causes the index to be calculated from pointer arithmetic and is therefore an expensive operation.

template<typename TImage>
const RegionType& itk::ImageReverseConstIterator< TImage >::GetRegion (  )  const [inline]

Definition at line 352 of file itkImageReverseConstIterator.h.

template<typename TImage>
void itk::ImageReverseConstIterator< TImage >::GoToEnd ( void   )  [inline]

Move an iterator to the end of the region. "End" for a reverse iterator is defined as one pixel before the first pixel in the region.

Reimplemented in itk::ImageRegionReverseConstIterator< TImage >.

Definition at line 364 of file itkImageReverseConstIterator.h.

template<typename TImage>

template<typename TImage>
bool itk::ImageReverseConstIterator< TImage >::IsAtEnd ( void   )  [inline]

Is the iterator at the end of the (reverse) region? "End" for a reverse iterator is one pixel before the first pixel in the region.

template<typename TImage>
itk::ImageReverseConstIterator< TImage >::itkStaticConstMacro ( ImageIteratorDimension  ,
unsigned  int,
TImage::ImageDimension   
)

Dimension of the image the iterator walks. This constant is needed so 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.

template<typename TImage>
bool itk::ImageReverseConstIterator< TImage >::operator!= ( const Self it  )  const [inline]

Comparison operator. Two iterators are the same if they "point to" the same memory location
