Member Function Documentation

template<class SView , class RView >
Actor * Gecode::Set::Element::ElementUnionConst< SView, RView >::copy ( Space home  )  [inline, virtual]

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 109 of file unionConst.hpp.

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

Cost function.

Implements Gecode::Propagator.

Definition at line 67 of file unionConst.hpp.

template<class SView , class RView >
void Gecode::Set::Element::ElementUnionConst< SView, RView >::reschedule ( Space home  )  [inline, virtual]

Schedule function.

Implements Gecode::Propagator.

Definition at line 73 of file unionConst.hpp.

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

Delete propagator and return its size.

Reimplemented from Gecode::Actor.

Definition at line 80 of file unionConst.hpp.

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

Perform propagation.

Implements Gecode::Propagator.

Definition at line 115 of file unionConst.hpp.

template<class SView , class RView >
ExecStatus Gecode::Set::Element::ElementUnionConst< SView, RView >::post ( Home  home,
SView  z,
const IntSetArgs x,
RView  y 
) [inline, static]

Post propagator for $ z=\bigcup\langle s_0,\dots,s_{n-1}\rangle[y] $

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