itk::VectorImageNeighborhoodAccessorFunctor< TImage > Class Template Reference

#include <itkVectorImageNeighborhoodAccessorFunctor.h>

Detailed Description

template<class TImage>
class itk::VectorImageNeighborhoodAccessorFunctor< TImage >

Provides accessor interfaces to Access pixels and is meant to be used on pointers to pixels held by the Neighborhood class.

A typical user should not need to use this class. The class is internally used by the neighborhood iterators.

PixelType itk::VectorImageNeighborhoodAccessorFunctor< TImage >::Get ( const InternalPixelType pixelPointer) const
inline

Method to dereference a pixel pointer. This is used from the ConstNeighborhoodIterator as the equivalent operation to (*it). This method should be preferred over the former (*it) notation. The reason is that dereferencing a pointer to a location of VectorImage pixel involves a different operation that simply dereferencing the pointer. Here a PixelType (array of InternalPixelType s) is created on the stack and returned.

void itk::VectorImageNeighborhoodAccessorFunctor< TImage >::SetBegin ( const InternalPixelType begin)
inline

Set the pointer index to the start of the buffer. This must be set by the iterators to the starting location of the buffer. Typically a neighborhood iterator iterating on a neighborhood of an Image, say image will set this in its constructor. For instance:

ConstNeighborhoodIterator( radius, image, )
{
...
m_NeighborhoodAccessorFunctor.SetBegin( image->GetBufferPointer() );
}
