~SurfelAdjacency()

template<Dimension dim>

DGtal::SurfelAdjacency< dim >::~SurfelAdjacency

(

)

SurfelAdjacency() [1/2]

template<Dimension dim>

DGtal::SurfelAdjacency< dim >::SurfelAdjacency

(

bool

int2ext

)

Constructor.

Parameters

int2ext

when 'true', the surfel adjacency is interior to exterior for any coordinate pair, when 'false', it is exterior to interior for any one.

NB:

setAdjacency to modify a specific pair or coordinates

SurfelAdjacency() [2/2]

template<Dimension dim>

DGtal::SurfelAdjacency< dim >::SurfelAdjacency

(

const SurfelAdjacency< dim > &

other

)

Copy constructor.

Parameters

other

the object to clone.

Member Function Documentation

getAdjacency()

template<Dimension dim>

bool DGtal::SurfelAdjacency< dim >::getAdjacency	(	Dimension	i,
		Dimension	j
	)		const

Returns whether a coordinate pair is interior (true) or exterior (false) in the bel adjacency.

Parameters

i	first coordinate.
j	second coordinate ('j != i').

Returns

'true' if the surfel adjacency is interior to exterior for the coordinate pair '(i,j)', 'false' when it is exterior to interior.

isValid()

template<Dimension dim>

bool DGtal::SurfelAdjacency< dim >::isValid

(

)

const

Checks the validity/consistency of the object.

Returns

'true' if the object is valid, 'false' otherwise.

operator=()

template<Dimension dim>

SurfelAdjacency & DGtal::SurfelAdjacency< dim >::operator=

(

const SurfelAdjacency< dim > &

other

)

Assignment.

Parameters

other

the object to copy.

Returns

a reference on 'this'.

selfDisplay()

template<Dimension dim>

void DGtal::SurfelAdjacency< dim >::selfDisplay

(

std::ostream &

out

)

const

Writes/Displays the object on an output stream.

Parameters

out	the output stream where the object is written.

setAdjacency()

template<Dimension dim>

void DGtal::SurfelAdjacency< dim >::setAdjacency	(	Dimension	i,
		Dimension	j,
		bool	int2ext
	)

Set a coordinate pair as interior to exterior or exterior to interior in the surfel adjacency.

Parameters

i	first coordinate.
j	second coordinate (j != i).
int2ext	when 'true', the surfel adjacency is interior to exterior for the coordinate pair '(i,j)', when 'false', it is exterior to interior.

Field Documentation

myInt2Ext

template<Dimension dim>

boost::array<bool, dim*dim> DGtal::SurfelAdjacency< dim >::myInt2Ext

private

Memorizes if the surfel adjacency is interior to exterior (true) or exterior to interior (false) for any pair (i,j). The index of the pair (i,j) is 'i * m_ks.dim() + j'.
