Methods to link the Slot
Because this version of the class pertains to static S.E.

's, those methods actually do nothing and calls to it should be optimized away.

void _structure_attach (const S &other)
 Link a SetSlot to a structural element.


Detailed Description

template<typename S, typename Tag>
struct vcsn::SetSlot< S, Tag >

Type of the set_ attribute of the Element class.

Derives from SetSlotAttribute, a reference to a structural element to which an Element is related.

The actual implementation of SetSlot<S>, for a given structural element S, depends on the value of dynamic_traits<S>ret, which chooses which version of SetSlotAttribute to inherit from.

Additionally, the class can be meta-tagged when multiple inheritance for the same structural element S is needed. This meta-tag (second template argument) makes the type unique w.r.t. the tag type.

Constructor & Destructor Documentation

SetSlot (  )  [inline]

Trivial constructor.

Calls the inherited constructor from SetSlotAttribute.

Definition at line 113 of file slots.hxx.

SetSlot ( const SetSlot< S, Tag > &  other  )  [inline]

Trivial constructor.

Calls the inherited constructor from SetSlotAttribute.

Definition at line 118 of file slots.hxx.

SetSlot ( const S &  other  )  [inline]

Trivial constructor.

Calls the inherited constructor from SetSlotAttribute.

Definition at line 123 of file slots.hxx.


Member Function Documentation

const S & _structure_get (  )  const [inherited]

Access to the instance of the structural element.

Because this version of the class pertains to static S.E.'s, this accessor returns a NULL reference, most likely inappropriate for any other form of dereferencing other than accessing methods of the S.E. (which do not use the reference anyway).

Referenced by Series::monoid(), Series::semiring(), and Element::structure().

bool _structure_bound (  )  const [inherited]

Whether the current set slot is linked to a structural element.

This version always returns true.
