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.
