Detailed Description

template<typename TImage>
template<bool VIsConst>
class itk::ImageBufferRange< 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 ImageBufferRange::iterator, or ImageBufferRange::const_iterator!

QualifiedIterator() [2/3]

template<typename TImage>

template<bool VIsConst>

itk::ImageBufferRange< 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." \note `QualifiedIterator<VIsConst>` follows the C++ "Rule of Zero" when VIsConst is true: The other five "special member functions" of the class are then implicitly defaulted. When VIsConst is false, its copy-constructor is provided explicitly, but it still behaves the same as a default implementation.

QualifiedIterator() [3/3]

template<typename TImage>

template<bool VIsConst>

itk::ImageBufferRange< 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.
