Member Function Documentation

template<class SView , class RView >
Actor * Gecode::Set::Element::ElementUnion< SView, RView >::copy ( Space &  home,
bool  share 
) [virtual]

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 102 of file union.hpp.

template<class SView , class RView >
PropCost Gecode::Set::Element::ElementUnion< SView, RView >::cost ( const Space &  home,
const ModEventDelta &  med 
) const [virtual]

Cost function.

Implements Gecode::Propagator.

Definition at line 68 of file union.hpp.

template<class SView , class RView >
size_t Gecode::Set::Element::ElementUnion< SView, RView >::dispose ( Space &  home  )  [inline, virtual]

Delete propagator and return its size.

Reimplemented from Gecode::Actor.

Definition at line 74 of file union.hpp.

template<class SView , class RView >
ExecStatus Gecode::Set::Element::ElementUnion< SView, RView >::propagate ( Space &  home,
const ModEventDelta &  med 
) [virtual]

Perform propagation.

Implements Gecode::Propagator.

Definition at line 108 of file union.hpp.

template<class SView , class RView >
ExecStatus Gecode::Set::Element::ElementUnion< SView, RView >::post ( Home  home,
SView  z,
IdxViewArray &  x,
RView  y 
) [static]

Post propagator for $ z=\bigcup\langle x_0,\dots,x_{n-1}\rangle[y] $

If y is empty, z will be constrained to be empty (as an empty union is the empty set).
