template<typename T>

void mln::accu::nil< T >::init

(

)

[inline]

Manipulators.

template<typename T>

bool mln::accu::nil< T >::is_valid

(

)

const [inline]

Check whether this accu is able to return a result.

Always true here.

template<typename E>

template<typename T>

void mln::Accumulator< E >::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 '_').

Reimplemented in mln::accu::stat::variance< T, S, R >.

template<typename E>

template<typename T>

void mln::Accumulator< E >::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 T>

util::ignore mln::accu::nil< T >::to_result

(

)

const [inline]

Get the value of the accumulator.
