Member Enumeration Documentation

template<typename TImage>
anonymous enum
inherited

Dimension of the image the iterator walks. This enum 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.

Enumerator
ImageIteratorDimension

Constructor & Destructor Documentation

template<typename TImage >
itk::ImageReverseIterator< TImage >::ImageReverseIterator ( )

Default constructor. Needed since we provide a cast constructor.

Definition at line 27 of file itkImageReverseIterator.hxx.

template<typename TImage >
itk::ImageReverseIterator< TImage >::ImageReverseIterator ( ImageType ptr,
const RegionType region 
)

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

Definition at line 33 of file itkImageReverseIterator.hxx.

template<typename TImage >
itk::ImageReverseIterator< TImage >::ImageReverseIterator ( const ImageIteratorWithIndex< TImage > &  it)

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

Definition at line 39 of file itkImageReverseIterator.hxx.

template<typename TImage >
itk::ImageReverseIterator< TImage >::ImageReverseIterator ( const ImageRegionReverseConstIterator< TImage > &  it)
protected

the construction from a const iterator is declared protected in order to enforce const correctness.

Definition at line 45 of file itkImageReverseIterator.hxx.

Member Function Documentation

template<typename TImage>
const PixelType itk::ImageReverseConstIterator< TImage >::Get ( void  ) const
inlineinherited
template<typename TImage>
static unsigned int itk::ImageReverseConstIterator< TImage >::GetImageIteratorDimension ( )
inlinestaticinherited

Get the dimension (size) of the index.

Definition at line 279 of file itkImageReverseConstIterator.h.

template<typename TImage>
const IndexType itk::ImageReverseConstIterator< TImage >::GetIndex ( void  )
inlineinherited

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

template<typename TImage>

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

template<typename TImage>
Self& itk::ImageRegionReverseConstIterator< TImage >::operator++ ( )
inlineinherited

iterator's index. For a reverse iterator, this moves backwards through the region. This operator will constrain the iterator within the region (i.e. the iterator will automatically wrap from the start of the row of the region to the end of the previous row of the region) up until the iterator tries to moves before the first pixel of the region. Here, the iterator will be set to be one pixel before the start of the region.

template<typename TImage>
Self& itk::ImageRegionReverseConstIterator< TImage >::operator-- ( )
inlineinherited

Decrement (prefix) the fastest moving dimension of the iterator's index. For a reverse iterator, this moves forward through the region. This operator will constrain the iterator within the region (i.e. the iterator will automatically wrap from the end of the row of the region to the start of the next row of the region) up until the iterator tries to moves past the last pixel of the region. Here, the iterator will be set to be one pixel past the end of the region.
