Member Function Documentation

bool mln::accu::logic::land_basic::can_stop ( ) const
inline

Test if it is worth for this accumulator to take extra data.

If the result is already 'false' (because this accumulator has already taken a 'false' value), can_stop returns true.

Definition at line 181 of file land_basic.hh.

void mln::accu::logic::land_basic::init ( )
inline

Manipulators.

Definition at line 140 of file land_basic.hh.

bool mln::accu::logic::land_basic::is_valid ( ) const
inline

Check whether this accu is able to return a result.

Always true here.

Definition at line 174 of file land_basic.hh.

void mln::Accumulator< land_basic >::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< land_basic >::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 '_').

bool mln::accu::logic::land_basic::to_result ( ) const
inline

Get the value of the accumulator.
