bool can_choose_non_starable ( SELECTOR(T)   )  const [inline, inherited]

Whether it is possible to call choose_non_starable.

There's no need for can_choose_starable, since Zero is always starable and therefore can be chosen.

Definition at line 46 of file semiring_base.hxx.

References vcsn::algebra::op_can_choose_non_starable(), and SELECT.

bool contains ( const Element< OtherS, T > &  other  )  const [inline, inherited]

Specialization of contains that always returns false.

Indeed, elements structured by a particular type are always incompatible with structural elements of another type.

self_t& self (  )  [inherited]

Accessor to the real type.

To be used by implementations in this class and derived structures to obtain a reference to the structural element with its most derived type.

const self_t& self (  )  const [inherited]

Accessor to the real type.

To be used by implementations in this class and derived structures to obtain a reference to the structural element with its most derived type.
