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.
