Detailed Description

Accumulator class counting the number of vertices adjacent to a set of mln::p_edges_psite (i.e., a set of edges).

The type to be count is mln::util::pix< pw::image<F, S> > where F and S are the parameters of this class.

This accumulator is used by mln::closing_area_on_vertices and mln::opening_area_on_vertices.

Member Function Documentation

template<typename F , typename S >

void mln::accu::count_adjacent_vertices< F, S >::init ( ) [inline]

Manipulators.

template<typename F , typename S >

bool mln::accu::count_adjacent_vertices< F, S >::is_valid ( ) const [inline]

Return whether this accu can return a result.

template<typename F , typename S >

void mln::accu::count_adjacent_vertices< F, S >::set_value ( unsigned c ) [inline]

Force the value of the counter to c.

void mln::Accumulator< count_adjacent_vertices< F, S > >::take_as_init ( const T & t ) [inherited]

Take as initialization the value t.

Dev note: this is a final method; override if needed by take_as_init_ (ending with '_').

void mln::Accumulator< count_adjacent_vertices< F, S > >::take_n_times	(	unsigned	n,
		const T &	t
	)			`[inherited]`

Take n times the value t.

Dev note: this is a final method; override if needed by take_as_init_ (ending with '_').

template<typename F , typename S >

unsigned mln::accu::count_adjacent_vertices< F, S >::to_result ( ) const [inline]

Get the value of the accumulator.
