template<typename L >

void mln::accu::count_labels< L >::init ( ) [inline]

Manipulators.

template<typename L >

bool mln::accu::count_labels< L >::is_valid ( ) const [inline]

Check whether this accu is able to return a result.

Always true here.

template<typename L >

void mln::accu::count_labels< L >::set_value ( unsigned c ) [inline]

Force the value of the counter to c.

Definition at line 155 of file count_labels.hh.

void mln::Accumulator< count_labels< L > >::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_labels< L > >::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 L >

unsigned mln::accu::count_labels< L >::to_result ( ) const [inline]

Get the value of the accumulator.
