Detailed Description

template<typename F, typename S>
struct mln::accu::count_adjacent_vertices< F, S >

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  )  [inline, 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 
) [inline, 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.
