Public Types

typedef Self self_t
 Exact type of the most derived type in the hierarchy.

Public Member Functions

template<typename T>
Element< Self, T > identity (SELECTOR(T)) const
 Returns the identity of the monoid (if mul_kind).
template<typename T>
Element< Self, T > zero (SELECTOR(T)) const
 Returns the zero of the monoid (if add_kind).
bool contains (const Element< Self, T > &elt) const
 Check if a given element is compatible with the structural element.
bool contains (const Element< OtherS, T > &other) const
 Specialization of contains that always returns false.
bool contains (const T &elt_value) const
 Check if an anonymous value is compatible with a structural element.
Element< Self, T > choose (SELECTOR(T)) const
 Choose randomly an element in the structure.
self_tself ()
 Accessor to the real type.
const self_tself () const
 Accessor to the real type.

Protected Member Functions

 MonoidBase ()
 Protected since it is an abstract class.
 MonoidBase (const MonoidBase &other)
 Protected since it is an abstract class.


Detailed Description

template<class Self>
struct vcsn::algebra::MonoidBase< Self >

The base class of all structures that are monoids.

Monoid defines identity for semigroups of mul_kind and zero for semigroup of add_kind.

Definition at line 41 of file monoid_base.hh.


Member Function Documentation

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.
