Constructor & Destructor Documentation

◆ const_iterator() [1/2]

template<unsigned int VDimension, bool VBeginAtZero>
itk::IndexRange< VDimension, VBeginAtZero >::const_iterator::const_iterator ( )
default

Default-constructor, as required for any C++11 Forward Iterator.

Note
The other five "special member functions" (copy-constructor, copy-assignment operator, move-constructor, move-assignment operator, and destructor) are defaulted implicitly, following the C++ "Rule of Zero".

◆ const_iterator() [2/2]

template<unsigned int VDimension, bool VBeginAtZero>
constexpr itk::IndexRange< VDimension, VBeginAtZero >::const_iterator::const_iterator ( const IndexType &  index,
const MinIndexType &  minIndex,
const IndexType &  maxIndex
