Constructor & Destructor Documentation

template<typename I >

template<typename Dps , typename Pref >

mln::dpoints_bkd_pixter< I >::dpoints_bkd_pixter	(	I &	image,
		const Dps &	dps,
		const Pref &	p_ref
	)			[inline]

Constructor (using an image).

Parameters:

[in]	image	The image to iterate over.
[in]	dps	An object (neighborhood or window) that can provide a set of delta-points.
[in]	p_ref	Center (resp. reference) point of the neighborhood (resp. window).

Definition at line 338 of file dpoints_pixter.hh.

template<typename Dps , typename Pref >

mln::dpoints_bkd_pixter< I >::dpoints_bkd_pixter	(	const Generalized_Pixel< Pref > &	pxl_ref,
		const Dps &	dps
	)			[inline]

Constructor (using a generalized pixel).

Parameters:

[in]	pxl_ref	Center (generalized) pixel to iterate around.
[in]	dps	An object (neighborhood or window) that can provide a set of delta-points.

template<typename I >

const I::value & mln::dpoints_bkd_pixter< I >::center_val

(

)

const [inline]

The value around which this iterator moves.

template<typename I >

void mln::dpoints_bkd_pixter< I >::invalidate

(

)

[inline]

Invalidate the iterator.

Definition at line 436 of file dpoints_pixter.hh.

template<typename I >

bool mln::dpoints_bkd_pixter< I >::is_valid

(

const [inline]

Test the iterator validity.

void mln::Iterator< dpoints_bkd_pixter< I > >::next

(

)

[inherited]

Go to the next element.

Warning:

This is a final method; iterator classes should not re-defined this method. The actual "next" operation has to be defined through the next_ method.

Precondition:

The iterator is valid.

template<typename I >

void mln::dpoints_bkd_pixter< I >::start

(

)

[inline]

Manipulation.

Start an iteration.
