Manipulators.

References mln::literal::zero.

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 &  v  )  [inline]

Set the return value of the accumalator.

void mln::Accumulator< sum< I, 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< sum< I, 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 I , typename S >
S mln::morpho::attribute::sum< I, S >::to_result (  )  const [inline]

Get the value of the accumulator.

template<typename I , typename S >
void mln::morpho::attribute::sum< I, S >::untake ( const argument &  v  )  [inline]

Untake a value from the accumulator.
