Constructor & Destructor Documentation

template<typename TImage>

itk::ImageRandomIteratorWithIndex< TImage >::ImageRandomIteratorWithIndex

(

)

Default constructor. Needed since we provide a cast constructor.

template<typename TImage>

itk::ImageRandomIteratorWithIndex< TImage >::ImageRandomIteratorWithIndex	(	ImageType *	ptr,
		const RegionType &	region
	)

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

template<typename TImage>

itk::ImageRandomIteratorWithIndex< TImage >::ImageRandomIteratorWithIndex

(

const ImageIteratorWithIndex< TImage > &

it

)

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

template<typename TImage>

itk::ImageRandomIteratorWithIndex< TImage >::ImageRandomIteratorWithIndex

(

const ImageRandomConstIteratorWithIndex< TImage > &

it

)

[protected]

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