mmcfilters::ContourEdgeRange::iterator Class Reference

Forward iterator that unpacks contour edges on dereference. More...

#include <ContourTrace.hpp>

Public Types
using	iterator_category = std::forward_iterator_tag
	Standard category for a multi-pass forward iterator.
using	value_type = ContourEdge
	Unpacked edge value yielded by dereference.
using	difference_type = std::ptrdiff_t
	Signed iterator-distance type.
using	pointer = void
	No pointer type is exposed because dereference returns a value.
using	reference = value_type
	Value-returning reference type.

Public Member Functions
	iterator (const int *packedEdge)
	Creates an iterator at one packed-edge position.
value_type	operator* () const
	Returns the unpacked current edge.
iterator &	operator++ ()
	Advances to the next packed edge.
iterator	operator++ (int)
	Advances while retaining the previous iterator position.

Friends
bool	operator== (const iterator &, const iterator &)=default
	Compares packed-edge positions.

Constructor & Destructor Documentation

iterator()

mmcfilters::ContourEdgeRange::iterator::iterator ( const int *  packedEdge )

inlineexplicit

Creates an iterator at one packed-edge position.

Parameters

packedEdge

Current packed-edge address.

Definition at line 101 of file ContourTrace.hpp.

Member Function Documentation

operator*()

value_type mmcfilters::ContourEdgeRange::iterator::operator* ( ) const

inline

Returns the unpacked current edge.

Returns

Current contour edge.

Definition at line 107 of file ContourTrace.hpp.

operator++() [1/2]

iterator & mmcfilters::ContourEdgeRange::iterator::operator++ ( )

inline

Advances to the next packed edge.

Returns

This iterator after advancing.

Definition at line 113 of file ContourTrace.hpp.

operator++() [2/2]

iterator mmcfilters::ContourEdgeRange::iterator::operator++ ( int  )

inline

Advances while retaining the previous iterator position.

Returns

Iterator at the position preceding the advance.
