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.

Additionnally, 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.

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 Element::structure().

bool _structure_bound  )  const [inherited]
 

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

This version always returns true.
