Return variable implementation of view.
View Gecode::DerivedView< View >::base | ( | void | ) | const |

void Gecode::DerivedView< View >::subscribe | ( | Space & | home, |
Propagator & | p, | ||
PropCond | pc, | ||
bool | schedule = true |
||
) |
Subscribe propagator p with propagation condition pc to view.
In case schedule is false, the propagator is just subscribed but not scheduled for execution (this must be used when creating subscriptions during propagation).
void Gecode::DerivedView< View >::cancel | ( | Space & | home, |
Propagator & | p, | ||
PropCond | pc | ||
) |
Cancel subscription of propagator p with propagation condition pc to view.
void Gecode::DerivedView< View >::reschedule | ( | Space & | home, |
Propagator & | p, | ||
PropCond | pc | ||
) |
Re-schedule propagator p with propagation condition pc.
void Gecode::DerivedView< View >::subscribe | ( | Space & | home, |
Advisor & | a, | ||
bool | fail = false |
||
) |
Subscribe advisor a to view.
If fail is true, run the advisor also on failure. This feature is undocumented.
void Gecode::DerivedView< View >::cancel | ( | Space & | home, |
Advisor & | a, | ||
bool | fail = false |
||
) |
Cancel subscription of advisor a.
|
static |
Return modification event.
void Gecode::DerivedView< View >::update | ( | Space & | home, |
bool | share, | ||
DerivedView< View > & | y | ||
) |
Update this view to be a clone of view y.
