Member Function Documentation

Actor * Gecode::Set::Element::ElementUnion::copy ( Space home,
bool  share 
) [virtual]

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 99 of file union.hpp.

PropCost Gecode::Set::Element::ElementUnion::cost ( const Space home,
const ModEventDelta med 
) const [virtual]

Cost function.

Implements Gecode::Propagator.

Definition at line 65 of file union.hpp.

size_t Gecode::Set::Element::ElementUnion::dispose ( Space home) [inline, virtual]

Delete propagator and return its size.

Reimplemented from Gecode::Actor.

Definition at line 72 of file union.hpp.

ExecStatus Gecode::Set::Element::ElementUnion::propagate ( Space home,
const ModEventDelta med 
) [virtual]

Perform propagation.

Implements Gecode::Propagator.

Definition at line 105 of file union.hpp.

ExecStatus Gecode::Set::Element::ElementUnion::post ( Home  home,
IdxViewArray x,
View0  y,
View1  z 
) [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).

Definition at line 86 of file union.hpp.
