Definition at line 107 of file accu/nil.hh.

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".

void mln::accu::nil< T >::take_as_init_ ( const argument  )  [inline]

Definition at line 114 of file accu/nil.hh.

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.
