template<class
Val, class UnsVal>
class Gecode::Int::ScaleView< Val, UnsVal >
Scale integer view (template).
A scale integer view \(s\) for an integer view \(x\) and a non-negative integer \(a\) provides operations such that \(s\) behaves as \(a\cdot x\).
The precision of a scale integer view is defined by the value types Val and UnsVal. Val can be either int or long long int where UnsVal must be the unsigned variant of Val. The range which is allowed for the two types is defined by the values in Gecode::Limits.
Note that scale integer views currently do not provide operations for updating domains by range iterators.
The template is not to be used directly (as it is very clumsy). Use the following instead:
