Constructor & Destructor Documentation

template<class TImage, class TFunction> itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::FloodFilledFunctionConditionalConstIterator (  const ImageType *    imagePtr, FunctionType *    fnPtr, IndexType    startIndex )

Constructor establishes an iterator to walk a particular image and a particular region of that image. This version of the constructor uses an explicit seed pixel for the flood fill, the "startIndex"

template<class TImage, class TFunction> itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::FloodFilledFunctionConditionalConstIterator (  const ImageType *    imagePtr, FunctionType *    fnPtr, std::vector< IndexType > &    startIndices )

Constructor establishes an iterator to walk a particular image and a particular region of that image. This version of the constructor uses a list of seed pixels for the flood fill

template<class TImage, class TFunction> itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::FloodFilledFunctionConditionalConstIterator (  const ImageType *    imagePtr, FunctionType *    fnPtr )

Constructor establishes an iterator to walk a particular image and a particular region of that image. This version of the constructor should be used when the seed pixel is unknown

template<class TImage, class TFunction> virtual itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::~FloodFilledFunctionConditionalConstIterator (    )  [inline, virtual]

Default Destructor. Definition at line 109 of file itkFloodFilledFunctionConditionalConstIterator.h. References itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::IndexType.

template<class TImage, class TFunction> void itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::FindSeedPixel (    )

Automatically find a seed pixel and set m_StartIndex. Does nothing if a seed pixel isn't found. A seed pixel is determined by traversing the input image's image's LargestPossibleRegion and applying the IsPixelIncluded() test.

template<class TImage, class TFunction> void itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::FindSeedPixels (    )

Automatically find all seed pixels.

template<class TImage, class TFunction> const PixelType& itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::Get (  void    )  const [inline, virtual]

template<class TImage, class TFunction> const IndexType itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::GetIndex (  void    )  [inline, virtual]

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. See also: SetIndex Implements itk::ConditionalConstIterator< TImage >. Definition at line 130 of file itkFloodFilledFunctionConditionalConstIterator.h. References itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::m_IndexStack.

Get the dimension (size) of the index. Reimplemented from itk::ConditionalConstIterator< TImage >. Definition at line 123 of file itkFloodFilledFunctionConditionalConstIterator.h.

template<class TImage, class TFunction> void itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::GoToBegin (  void    )  [inline]

Move an iterator to the beginning of the region. "Begin" is defined as the first pixel in the region. Definition at line 157 of file itkFloodFilledFunctionConditionalConstIterator.h. References itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::m_IndexStack.

template<class TImage, class TFunction> void itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::InitializeIterator (    )

Initializes the iterator, called from constructor

template<class TImage, class TFunction> bool itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::IsAtEnd (    )  [inline, virtual]

Is the iterator at the end of the region? Implements itk::ConditionalConstIterator< TImage >. Definition at line 138 of file itkFloodFilledFunctionConditionalConstIterator.h. References itk::ConditionalConstIterator< TImage >::m_IsAtEnd.

Compute whether the index of interest should be included in the flood Implements itk::ConditionalConstIterator< TImage >. Implemented in itk::FloodFilledImageFunctionConditionalConstIterator< TImage, TFunction >, and itk::FloodFilledSpatialFunctionConditionalConstIterator< TImage, TFunction >.

template<class TImage, class TFunction> itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::itkStaticConstMacro (  NDimensions   , unsigned    int, TImage::ImageDimension    )

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. Reimplemented from itk::ConditionalConstIterator< TImage >. Reimplemented in itk::FloodFilledFunctionConditionalIterator< TImage, TFunction >.

template<class TImage, class TFunction> void itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::operator++ (    )  [inline, virtual]

Walk forward one index Implements itk::ConditionalConstIterator< TImage >. Definition at line 187 of file itkFloodFilledFunctionConditionalConstIterator.h.

template<class TImage, class TFunction> Self& itk::FloodFilledFunctionConditionalConstIterator< TImage, TFunction >::operator= (  const Self &    it )  [inline]

operator= is provided to make sure the handle to the image is properly reference counted. Reimplemented from itk::ConditionalConstIterator< TImage >. Reimplemented in itk::FloodFilledFunctionConditionalIterator< TImage, TFunction >. Definition at line 116 of file itkFloodFilledFunctionConditionalConstIterator.h.
