Detailed Description

template<class VA, class VB, class VC>
class Gecode::Int::Element::ViewDom< VA, VB, VC >

Domain consistent element propagator for array of views.

The propagator uses staging: first it uses bounds-propagation on the array of views and the uses domain-propagation on the array of views.
