Detailed Description
template<typename S, bool dynamic>
struct vcsn::SetSlotAttribute< S, dynamic >
Base class for SetSlot.
This class is responsible for holding a reference to the structural element in each Element instance, by means of its set_ attribute.
This version (parameter dynamic is false) is used when the structural element is static, i.e. does not require a S.E. instance reference in all related Element instance objects: all its properties are carried by its type.
Because this version has actually no attribute, it should take no memory space in each SetSlot (then Element) instance to which it is linked.

| const S & _structure_get | ( | ) | const |
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).
