dip::PixelTableOffsets::iterator class

An iterator that visits each of the neighborhood’s pixels in turn.

Dereferencing the iterator returns an offset. Satisfies the requirements for ForwardIterator.

Constructors, destructors, assignment and conversion operators

iterator() defaulted: Default constructor yields an invalid iterator that cannot be dereferenced.
iterator(dip::PixelTableOffsets const& pt) explicit: Constructs an iterator to the first pixel in the neighborhood.

using iterator_category = std::forward_iterator_tag: Iterator category.
using value_type = dip::sint: The value obtained by dereferencing is an offset.
using reference = dip::sint: The type of a reference, but we don’t return by reference, it’s just as easy to copy.

static auto end(dip::PixelTableOffsets const& pt) -> dip::PixelTableOffsets::iterator: Constructs an end iterator.
void swap(dip::PixelTableOffsets::iterator& other) noexcept: Swap.
auto Offset() const -> dip::PixelTableOffsets::iterator::reference: Get offset, identical to dereferencing.
auto Index() const -> dip::uint: Get index within run.
auto IsAtEnd() const -> bool: Test to see if the iterator reached past the last pixel.

auto operator*() const -> dip::PixelTableOffsets::iterator::reference: Dereference.
auto operator++() -> dip::PixelTableOffsets::iterator&: Pre-increment.
auto operator++(int ) -> dip::PixelTableOffsets::iterator: Post-increment.
auto operator==(dip::PixelTableOffsets::iterator const& other) const -> bool: Equality comparison, is true if the two iterators reference the same pixel in the same pixel table, even if they use the strides of different images.
auto operator!=(dip::PixelTableOffsets::iterator const& other) const -> bool: Inequality comparison.
auto operator bool() const -> bool explicit: Test to see if the iterator is still pointing at a pixel.
