Function Documentation

template<unsigned D, typename G>

void mln::topo::detach	(	const complex_psite< D, G > &	f,
		complex_image< D, G, bool > &	ima
	)			[inline]

Detach the cell corresponding to f from ima.

Precondition:

f is a facet (it does not belong to any face of higher dimension).

ima is an image of Boolean values.

algebraic_n_face< 1, D > mln::topo::edge	(	const n_face< 0, D > &	f1,
		const n_face< 0, D > &	f2
	)			[inline]

Helpers.

Return the algebraic 1-face (edge) linking the 0-faces (vertices) f1 and f2. If there is no 1-face between f1 and f2, return an invalid 1-face.

Precondition:

f1 and f2 must belong to the same complex.

Note: this routine assumes the complex is not degenerated, i.e,

• it does not check that f1 and f2 are the only 0-faces adjacent to an hypothetical 1-face; it just checks that f1 and f2 share a common 1-face;

• if there are several ajacent 1-faces shared by f1 and f2 (if the complex is ill-formed), there is no guarantee on the returned 1-face (the current implementation return the first 1-face found, but client code should not rely on this implementation-defined behavior).
