itk::ImageBufferRange< TImage >::QualifiedIterator< VIsConst > Class Template Referencefinal

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
The other five "special member functions" are defaulted implicitly, following the C++ "Rule of Zero".

◆ QualifiedIterator() [3/3]

template<typename TImage>
template<bool VIsConst>
template<bool VIsArgumentConst, typename = std::enable_if_t<VIsConst && !VIsArgumentConst>>
itk::ImageBufferRange< TImage >::QualifiedIterator< VIsConst >::QualifiedIterator ( const QualifiedIterator< VIsArgumentConst > &  arg)
inlinenoexcept

Constructor for implicit conversion from non-const to const iterator.
