Domain tests



bool range (void) const
 Test whether domain is a range.

Domain update by iterator

Views can be both updated by range and value iterators. Value iterators do not need to be strict in that the same value is allowed to occur more than once in the iterated sequence.

The argument depends must be true, if the iterator passed as argument depends on the view on which the operation is invoked. In this case, the view is only updated after the iterator has been consumed. Otherwise, the domain might be updated concurrently while following the iterator.

ModEvent narrow_r (Space &home, I &i, bool depends=true)
 Replace domain by ranges described by i.
template<class I >
ModEvent inter_r (Space &home, I &i, bool depends=true)
 Intersect domain with ranges described by i.
template<class I >
ModEvent minus_r (Space &home, I &i, bool depends=true)

ModEvent inter_v (Space &home, I &i, bool depends=true)

Delta information for advisors



int min (const Delta &d) const
 Return minimum value just pruned.
int max (const Delta &d) const
 Return maximum value just pruned.
bool any (const Delta &d) const
 Test whether arbitrary values got pruned.

View-dependent propagator support



static ModEventDelta med (ModEvent me)
 Translate modification event me to modification event delta for view.
