Detailed Description

template<typename TImage>
template<bool VIsConst>
class itk::Experimental::ImageRegionRange< TImage >::QualifiedIterator< VIsConst >

Iterator class that is either 'const' or non-const qualified. A non-const qualified instantiation of this template allows the pixel that it points to, to be modified. A const qualified instantiation does not.

Note
The definition of this class is private. Please use its type alias ImageRegionRange::iterator, or ImageRegionRange::const_iterator!

◆ QualifiedIterator() [2/3]

template<typename TImage >
template<bool VIsConst>
itk::Experimental::ImageRegionRange< TImage >::QualifiedIterator< VIsConst >::QualifiedIterator ( )
default

Default-constructor, as required for any C++11 Forward Iterator. Offers the guarantee added to the C++14 Standard: "value-initialized iterators may be compared and shall compare equal to other value-initialized iterators of the same type."

◆ QualifiedIterator() [3/3]

template<typename TImage >
template<bool VIsConst>
itk::Experimental::ImageRegionRange< TImage >::QualifiedIterator< VIsConst >::QualifiedIterator ( const QualifiedIterator< false > &  arg)
inlinenoexcept

Constructor that allows implicit conversion from non-const to const iterator. Also serves as copy-constructor of a non-const iterator.

Definition at line 217 of file itkImageRegionRange.h.

◆ ~QualifiedIterator()

template<typename TImage >
template<bool VIsConst>
itk::Experimental::ImageRegionRange< TImage >::QualifiedIterator< VIsConst >::~QualifiedIterator ( )
default

Explicitly-defaulted destructor.
