[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.

util::ignore mln::accu::internal::base< util::ignore , nil< T > >::subj_

)

[inherited]

template<typename T >

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

(

const argument &

)

[inline]

void mln::Accumulator< nil< T > >::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< nil< T > >::take_as_init_

(

const T &

t

)

[inherited]

Default implementation of "take as initialization".

template<typename T >

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

(

const argument &

)

[inline]

void mln::Accumulator< nil< T > >::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 '_').

void mln::Accumulator< nil< T > >::take_n_times_	(	unsigned	n,
		const T &	t
	)			[inherited]

Default implementation of "take n times".

template<typename T >

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

(

)

const [inline]

Get the value of the accumulator.
