Detailed Description

template<typename T>
struct mln::accu::nil< T >

Definition at line 49 of file accu/nil.hh.

Constructor & Destructor Documentation

template<typename T >
mln::accu::nil< T >::nil ( )

Member Function Documentation

template<typename T >
void mln::accu::nil< T >::init ( )

Manipulators.

template<typename T >
bool mln::accu::nil< T >::is_valid ( ) const

Check whether this accu is able to return a result.

Always true here.

template<typename T >
void mln::accu::nil< T >::take ( const argument )
template<typename T >
void mln::accu::nil< T >::take ( const nil< T > &  )
void mln::Accumulator< nil< T > >::take_as_init ( const T t)
inherited

Take as initialization the value t.

template<typename T >
void mln::accu::nil< T >::take_as_init_ ( const argument )
void mln::Accumulator< nil< T > >::take_as_init_ ( const T t)
inherited

INTERNAL_API

Default implementation of "take as initialization".

void mln::Accumulator< nil< T > >::take_n_times ( unsigned  n,
const T t 
)
inherited

Take n times the value t.

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

INTERNAL_API

Default implementation of "take n times".

template<typename T >
util::ignore mln::accu::nil< T >::to_result ( ) const

Get the value of the accumulator.
