Member Function Documentation

template<class View , class View0 , class View1 >
Actor * Gecode::Set::Element::ElementIntersection< View, View0, View1 >::copy ( Space &  home,
bool  share 
) [inline, virtual]

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 104 of file inter.hpp.

template<class View , class View0 , class View1 >
PropCost Gecode::Set::Element::ElementIntersection< View, View0, View1 >::cost ( const Space &  home,
const ModEventDelta &  med 
) const [inline, virtual]

Cost function.

Implements Gecode::Propagator.

Definition at line 68 of file inter.hpp.

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

Delete propagator and return its size.

Reimplemented from Gecode::Actor.

Definition at line 75 of file inter.hpp.

template<class View , class View0 , class View1 >
ExecStatus Gecode::Set::Element::ElementIntersection< View, View0, View1 >::propagate ( Space &  home,
const ModEventDelta &  med 
) [inline, virtual]

Perform propagation.

Implements Gecode::Propagator.

Definition at line 110 of file inter.hpp.

template<class View , class View0 , class View1 >
ExecStatus Gecode::Set::Element::ElementIntersection< View, View0, View1 >::post ( Home  home,
IdxViewArray &  x,
View0  y,
View1  z,
const IntSet &  u 
) [inline, static]

Post propagator for $ z=\bigcap\langle x_0,\dots,x_{n-1}\rangle[y] $ using u as universe

If y is empty, z will be constrained to be the given universe u (as an empty intersection is the universe).
