Detailed Description

template<class TImage, class TBoundaryCondition = ZeroFluxNeumannBoundaryCondition< TImage >>
class itk::ConstNeighborhoodIterator< TImage, TBoundaryCondition >

Const version of NeighborhoodIterator, defining iteration of a local N-dimensional neighborhood of pixels across an itk::Image.

ConstNeighborhoodIterator implements the read-only methods of NeighborhoodIterator. It serves as a base class from which other iterators are derived. See NeighborhoodIterator for more complete information.

Returns true if the neighborhood index is within region boundaries, false otherwise. If false, then internalIndex and offset are calculated. Otherwise their values are left unchanged. Also updates an internal boolean array indicating which of the iterator's faces are out of bounds.

Parameters
n- linear neighborhood index.
internalIndex- calculated for index n only when the neighborhood is not completely within region boundaries.
offset- per-dimension offsets for index n to nearest boundary index, calculate only when the neighborhood is not completely within region boundaries.

Self& itk::ConstNeighborhoodIterator< TImage, TBoundaryCondition >::operator-- ( )

Decrements the pointers in the ConstNeighborhoodIterator, wraps across boundaries automatically, accounting for the disparity in the buffer size and the region size of the image.

template<class TImage, class TBoundaryCondition = ZeroFluxNeumannBoundaryCondition< TImage >>
Self& itk::ConstNeighborhoodIterator< TImage, TBoundaryCondition >::operator-= ( const OffsetType )

Subtraction of an itk::Offset. Note that this method does not do any bounds checking. Subtracting an offset that moves the iterator out of its assigned region will produce undefined results.

bool itk::ConstNeighborhoodIterator< TImage, TBoundaryCondition >::operator< ( const Self it) const
inline

Returns a boolean < comparison of the memory addresses of the center elements of two ConstNeighborhoodIterators of like pixel type and dimensionality. The radii of the iterators are ignored.

virtual void itk::ConstNeighborhoodIterator< TImage, TBoundaryCondition >::OverrideBoundaryCondition ( const ImageBoundaryConditionPointerType  i)
inlinevirtual

Allows a user to override the internal boundary condition. Care should be taken to ensure that the overriding boundary condition is a persistent object during the time it is referenced. The overriding condition can be of a different type than the default type as long as it is a subclass of ImageBoundaryCondition.

void itk::ConstNeighborhoodIterator< TImage, TBoundaryCondition >::SetLocation ( const IndexType position)

This method positions the iterator at an indexed location in the image. SetLocation should NOT be used to update the position of the iterator during iteration, only for initializing it to a position prior to iteration. This method is not optimized for speed.
