template<typename I, typename S>

bool mln::morpho::attribute::sum< I, S >::is_valid

(

)

const [inline]

Check whether this accu is able to return a result.

Return always true.

template<typename I, typename S>

void mln::morpho::attribute::sum< I, S >::set_value

(

const argument &

t

)

[inline, inherited]

Take as initialization the value t.
