Detailed Description

template<typename T, typename S = typename mln::value::props< T >::sum, typename M = S>
struct mln::accu::stat::mean< T, S, M >

Generic mean accumulator class.

Parameter T is the type of values that we sum. Parameter S is the type to store the sum of values; the default type of S is the summation type (property) of T. Parameter M is the type of the mean value; the default type of M is S.

template<typename T , typename S , typename M >
bool mln::accu::stat::mean< T, S, M >::is_valid (  )  const [inline]

Check whether this accu is able to return a result.

Always true here.

template<typename T , typename S , typename M >
accu::math::sum< T >::result mln::accu::stat::mean< T, S, M >::sum (  )  const [inline]

Get the sum of values.

Definition at line 251 of file accu/stat/mean.hh.

void mln::Accumulator< mean< T, S, M > >::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< mean< T, S, M > >::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 '_').

template<typename T , typename S , typename M >
M mln::accu::stat::mean< T, S, M >::to_result (  )  const [inline]

Get the value of the accumulator.
