Base-class for variable implementation views. More...
#include <view.hpp>
Public Types | |
typedef Var | VarType |
The variable type corresponding to the view. | |
typedef Var::VarImpType | VarImpType |
The variable implementation type corresponding to the view. |
Protected Member Functions | |
VarImpView (void) | |
Default constructor. | |
VarImpView (VarImpType *y) | |
Initialize with variable implementation y. | |
void | varimp (VarImpType *y) |
Set variable implementation to y. |
Protected Attributes | |
VarImpType * | x |
Pointer to variable implementation. |
Generic view information | |
static bool | varderived (void) |
Return whether this view is derived from a VarImpView. | |
VarImpType * | varimp (void) const |
Return variable implementation of view. | |
unsigned int | degree (void) const |
Return degree (number of subscribed propagators and advisors) | |
double | afc (void) const |
Return accumulated failure count. |
View-dependent propagator support | |
static void | schedule (Space &home, Propagator &p, ModEvent me) |
Schedule propagator p with modification event me. | |
static ModEvent | me (const ModEventDelta &med) |
Return modification event for view type in med. | |
static ModEventDelta | med (ModEvent me) |
Translate modification event me to modification event delta for view. |
Delta information for advisors | |
static ModEvent | modevent (const Delta &d) |
Return modification event. |
Domain tests | |
bool | assigned (void) const |
Test whether view is assigned. |
Dependencies | |
void | subscribe (Space &home, Propagator &p, PropCond pc, bool schedule=true) |
Subscribe propagator p with propagation condition pc to view. | |
void | cancel (Space &home, Propagator &p, PropCond pc) |
Cancel subscription of propagator p with propagation condition pc to view. | |
void | reschedule (Space &home, Propagator &p, PropCond pc) |
Re-schedule propagator p with propagation condition pc. | |
void | subscribe (Space &home, Advisor &a, bool fail=false) |
Subscribe advisor a to view. | |
void | cancel (Space &home, Advisor &a, bool fail=false) |
Cancel subscription of advisor a. |
Cloning | |
void | update (Space &home, VarImpView< Var > &y) |
Update this view to be a clone of view y. |
Ordering | |
bool | operator< (const VarImpView &y) const |
Whether this view comes before view y (arbitray order) |
