bool	contains (const Element< OtherS, T > &other) const
	Specialization of containts that always return false.
bool	contains (const T &elt_value) const
	Check if an anonymous value is compatible with a structural element.

	Choose randomly an element in the structure.

Detailed Description

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

SemigroupBase is the base class of all structures that are semigroups.

All derived classes must define type virtual_types<S>::semigroup_kind.

Member Function Documentation

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

Specialization of containts that always return 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. This accessor is intended to be used by implementations in this class and derivated structures to obtain a reference to the structural element with its most derivated type.
