"Logical-and" accumulator.
Conversely to accu::logic::land, this version does not have the 'untake' method but features the 'can_stop' method.

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.
