Detailed Description

template<typename S>
struct vcsn::SetSlotAttribute< S, true >

Base class for SetSlot, specializing SetSlotAttribute.

This class is a specialization of SetSlotAttribute used when the structural element is dynamic, i.e. requires a S.E. instance reference in all related Element instance objects.

Constructor & Destructor Documentation

SetSlotAttribute (  const SetSlotAttribute< S, true > &  other  )

Copy constructor. Create a structural element reference by copying from the other attribute. Definition at line 73 of file slots.hxx.

SetSlotAttribute (  const S &  other  )

Foreign copy constructor. Create a structural element reference by copying from a reference to a S.E. instance defined elsewhere. Bug: For a number of reasons (see the mailing list), this constructor creates a fresh copy on the heap which is never deallocated. Bug: Make a better self-contained description of the bug. Definition at line 78 of file slots.hxx.
