Dependencies

void void Gecode::VarImp< VIC >::subscribe (Space &home, Propagator &p, PropCond pc, bool assigned, ModEvent me, bool schedule) subscribe Space & home Propagator & p PropCond pc bool assigned ModEvent me bool schedule Subscribe propagator p with propagation condition pc. In case schedule is false, the propagator is just subscribed but not scheduled for execution (this must be used when creating subscriptions during propagation).In case the variable is assigned (that is, assigned is true), the subscribing propagator is scheduled for execution. Otherwise, the propagator subscribes and is scheduled for execution with modification event me provided that pc is different from PC_GEN_ASSIGNED. void forceinline void Gecode::VarImp< VIC >::cancel (Space &home, Propagator &p, PropCond pc, bool assigned) cancel Space & home Propagator & p PropCond pc bool assigned Cancel subscription of propagator p with propagation condition pc. If the variable is assigned, assigned must be true. void forceinline void Gecode::VarImp< VIC >::subscribe (Space &home, Advisor &a, bool assigned) subscribe Space & home Advisor & a bool assigned Subscribe advisor a to variable. The advisor a is only subscribed if assigned is false. void forceinline void Gecode::VarImp< VIC >::cancel (Space &home, Advisor &a, bool assigned) cancel Space & home Advisor & a bool assigned Cancel subscription of advisor a. If the variable is assigned, assigned must be true. unsigned int forceinline unsigned int Gecode::VarImp< VIC >::degree (void) const degree void Return degree (number of subscribed propagators and advisors) Note that the degree of a variable implementation is not available during cloning. double forceinline double Gecode::VarImp< VIC >::afc (const Space &home) const afc const Space & home Return accumulated failure count (plus degree) Note that the accumulated failure count of a variable implementation is not available during cloning.

Cloning variables

forceinline Gecode::VarImp< VIC >::VarImp (Space &home, bool share, VarImp &x) VarImp Space & home bool share VarImp & x Constructor for cloning. bool forceinline bool Gecode::VarImp< VIC >::copied (void) const copied void Is variable already copied. VarImp * forceinline VarImp< VIC > * Gecode::VarImp< VIC >::forward (void) const forward void Use forward pointer if variable already copied. VarImp * VarImp* Gecode::VarImp< VIC >::next (void) const next void Return next copied variable.

Variable implementation-dependent propagator support

void forceinline void Gecode::VarImp< VIC >::schedule (Space &home, Propagator &p, ModEvent me, bool force=false) schedule Space & home Propagator & p ModEvent me bool force false Schedule propagator p with modification event me. If force is true, the propagator is re-scheduled (including cost computation) even though its modification event delta has not changed. ModEvent forceinline ModEvent Gecode::VarImp< VIC >::me (const ModEventDelta &med) me const ModEventDelta & med Project modification event for this variable type from med. ModEventDelta forceinline ModEventDelta Gecode::VarImp< VIC >::med (ModEvent me) med ModEvent me Translate modification event me into modification event delta. ModEvent forceinline ModEvent Gecode::VarImp< VIC >::me_combine (ModEvent me1, ModEvent me2) me_combine ModEvent me1 ModEvent me2 Combine modifications events me1 and me2.

Delta information for advisors

ModEvent forceinline ModEvent Gecode::VarImp< VIC >::modevent (const Delta &d) modevent const Delta & d Return modification event.

The base pointer of the array of subscribed actors.This pointer must be first to avoid padding on 64 bit machines. VarImp< VIC > * VarImp<VIC>* Gecode::VarImp< VIC >::fwd fwd Forwarding pointer. During cloning, this is used as the forwarding pointer for the variable. The original value is saved in the copy and restored after cloning. unsigned int forceinline unsigned int Gecode::VarImp< VIC >::idx [pc_max+1] idx Indices of subscribed actors. The entries from base[0] to base[idx[pc_max]] are propagators, where the entries between base[idx[pc-1]] and base[idx[pc]] are the propagators that have subscribed with propagation condition pc.The entries between base[idx[pc_max]] and base[idx[pc_max+1]] are the advisors subscribed to the variable implementation.
