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 when the structural element is dynamic, i.e. requires a S.E. instance reference in all related Element instance objects.

Member Function Documentation

SetSlotAttribute const SetSlotAttribute< S, true > &  other  ) 
 

Copy constructor.

This copy constructor creates an structural element reference by copying from the other attribute.

SetSlotAttribute const S &  other  ) 
 

Foreign copy constructor.

This copy constructor creates an 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.

void assign const SetSlotAttribute< S, true > &  other  ) 
 

Update the reference in the slot.

This method updates the S.E. reference in the attribute with the reference given as argument.

void attach const S &  s  ) 
 

Update the reference in the slot.

This method updates the S.E. reference in the attribute with the reference given as argument.
