◆ dispose()

template<class View, class View0, class View1>
size_t Gecode::Set::Element::ElementIntersection< View, View0, View1 >::dispose ( Space & home)
inlinevirtual

Delete propagator and return its size.

Reimplemented from Gecode::Actor.

Definition at line 77 of file inter.hpp.

◆ propagate()

template<class View, class View0, class View1>
